Sometimes your deposit address may be changed automatically after a software update.
However, the old address usually remains active for a certain period of time to make sure that all earlier transactions are completed.
We recommend that you regularly check your current address on your Account page and start using your new address as soon as you notice that it has changed.
The old address may be eventually deactivated, and you may receive an appropriate email notification, so please don’t overlook it.
If it has been a while and you still don't see your funds in your account, please check the article Where is my deposit?
