Description

Months ago I received several invites for conversations but by the time I saw them I could neither accept nor reject them anymore.

When trying to reject an invite I get:

Failed to leave room "!IaGVtVRpgDwQuKawsw:xxx.xxxx" through 1 server(s)

When trying to accept any of them:

You are not invited to this room.

Now I have 21 invites in my Element that I can neither accept nor reject.

Steps to reproduce

I am not exactly sure how that goes but it might be reproducible by

Invite a dendrite user from another instance into a chat
Wait a while for the invite to arrive on the dendrite server
Remove the channel from the origin server
On the dendrite client try to join / reject the invite.

This might be just an client/element error. Try clearing element's cache in Settings->Help & About->Clear cache and reload

I have that across multiple instances of clients (and platforms).

I have had similar problems when I manually deleted rooms and that resolved it for me. Try it out and see if that resolves it.

How do you manually delete a channel that you can't see?

By channel you mean a room? For synapse there is synapse-admin, but if the management API are compatible, you should be able to use it as well. There are other garbage collectors as well, and you can also manually curl the API. I personally prefer a VSCode extension to manually interface with some API.
