New JMAP interface bug in moving items
 

Moved "sent items" from the migrated folder to "sent" and emails are there but nothing displays. Logging out and in does not work.

Deleting folders also caused a "crash" was unable to copy the error lines to email support as copying was not allowed.

You need to raise a ticket; FM staff are very unlikely to read your complaint here.
