We are finally moving to a better container format for our Movim instance later this week. This will hopefully fix those persistent image preview issues we started having ever since switching to the old container format that lacks an image proxy.
The instance will be probably down for an hour or so as we need to reorganize a few things with the storage and overall setup.
Your access to the XMPP server with other apps should be unaffected.
Oh and in case you didn’t notice yet, Movim recently added Discord like voice channels that you should definitely give a try 👍
