There are two constraints in sending gift.

First, you can only send one gift in a day to each friend. Also, you can't send gift to your friend who have yet to collect the gift you send previously. In addition, your sending gifts sometimes don't arrive in your inbox, but it's caused by Facebook itself, which is beyond our control.
 
Your gifts don't disappear despite of  "An error has occurred. Please try again later"  message, disconnection, and freezing. The money is safely added to your chips balance and you'll see your balance increase when you log back.

No you can’t. Connection lost can happen due to a number of factors such as unstable local internet, wireless LAN, duplicate login attempts, and many other factors.
If your game had just been stopped or stuck, it is strongly recommended that you change your web browser to Chrome, update the flash player into the latest version,  and clear your browser's cache and cookies. Please refer to the FAQ on how to clear the cache and cookies (click to learn more).
Also, insufficient memory capacity of your PC can be one of the reasons.
You can refer to the FAQ  about connection lost issue.
 
According to reimbursement policy stated in Terms of service , we're originally not responsible for loss or damage in chips due to connection lost.

Posting issues can happen due to a number of factors. Some are beyond our control, some are not. Following are the factors. 

Following behaviors can lead to restrictions by Facebook.
 
• Restrictions by Facebook 
 
 - Too many shares of post in a short period of time
 
  - Excessive copy and paste, friend request, message, and the other request in a short period of time 
 
 - Inappropriate posts like pornography, spam, advertisement, and any other offense.
 
 - The other behaviors regulated by Facebook.
 
• Page view error: Sometimes you can't see your own posts on other user's wall, which is why you could misunderstand that your posts are not shared with them.
 
• Any other possible factors: Problems occurred by Facebook server, web browser, and any other reason.
 
 
Facebook doesn't inform you the exact period and reasons, and most of the restrictions are temporary. But, the period could be extended if you do inappropriate actions repeatedly. In this case, you'll definitely have trouble posting for a long time, or even be blocked permanently. In most cases, restrictions are temporary. Therefore, you should refrain from posting for the time being. But, if you have this problem consistently, you're strongly recommended to delete this app and re-sign in, and this will never influence your chip balance, experience level, mission badges, friends list, and any other status.
 

You can find the “Invite Friends” menu when you click the “Gifts” box icon on the bottom of the game screen.
Also, you can click “≡” on the right side of the game screen. You will see the “FRIENDS” section.
When you click on that section, you can send an “Invite” to friends.

You can collect gift by clicking "Collect All" or "Accept" button in your gift Inbox. "Collect All" button allows you to collect all the gifts in your inbox, and "Accept" button allows you collect just one of your gifts on the left of it.  This inbox pops up on the middle of game screen very frequently, and you can also open gift Inbox by clicking "Show inbox" icon at the bottom of game screen.

Please go to your Facebook Home page and tap “▼” on the right column.
Scroll down, tap “Settings & Privacy” then “Settings.”

Then tap “Apps and Websites” on the left side of the screen.
Tap the app or website that you want to remove.
Below the name of the app or website, tap “Remove.”
Tap “Remove” again to confirm.
 

You can collect gift by "Collect all" or " Accept" button. In normal cases, the money is added to your chip balance right after you collected gifts with an animation beneath your chips account. But, if your game screen is disconnected or frozen, collected money is automatically added to your account without animation. In other words, there is no loss of gift or collected money. Therefore you will see your chip balance is increased by the amount of gift money you collected before.

There are several reasons for this problem. In most cases, you probably clicked an expired event bonus link or already collected a bonus from it.

Most importantly, despite freezing or losing connection while you’re moving to the DoubleU app/site or in the middle of a bonus game, you don’t lose the bonus. If you go back to the game again, the bonus game will pop up and you will get your bonus successfully.

You can’t give your own chips to your friends directly. Instead, you can send bonus gifts to your friends, and also accept gifts from your friends. In addition, you can share bonus posts on your friends’ wall.
