Can not delete emails (gmail account)

[Riad]

Recently, after deleting messages from the GMail account, the messages seem at first to be deleted, but after synchronization they return back like they were never deleted.
I must use a computer to delete the messages.
Is there a solution for this problem?

Are you deleting messages by "move to deleted" (the trash can icon)?

And they come back after you check mail in the account?

Please check / fix the mapping of the app's "special" folders to server folders:

To restore the "mapping" of "special" (Sent, etc) folders to server folders, please do this:

- Long press the account
- Options and folders
- Folders

Let it refresh

- Find the Sent folder (under [Gmail]), tap its name, choose "Sync with [ Sent ]".
- Repeat for Deleted and Drafts, and possibly Spam and Archive (which Gmail calls All Mail).
