If you can not make any images at all, you maybe run in the same problem like me. Your storage space is full.
I wait for many months now for a fix…
It can be fixed by deleting conversations with images in the site bar.
but! NEVER DELETE THE CHATS IN THE SETTINGS!!!
It will not delete the images but only the chats, and you loos the possibility of any access. Your account will be blocked.
This will not stop until we get direct access to our data on the servers, and so we can manage the images directly.
