Bug description

After successful re-registration on a new device, no group membership information is fetched. New messages sent in these groups aren't received.
Some time later, a direct 1:1 message is sent to this re-registered account, which is however well received. This event somehow triggered something and unlocked the group membership fetching.

Steps to reproduce

• re-register account (with correct PIN), that is a member of several group chats
• nothing happens, no group membership information is fetched
• send a personnal message to this account
• fetching of group info finally unlocked

Actual result: Broken group membership fetching after re-registration
Expected result: Group membership should be loaded directly after re-registration

Device info

Signal version: 7.4.2

Can confirm this, I came here to write about this very bug. Despite being the administrator of a group, there was no way to log back in.

Can we get a debuglog?

Hello, I can try to reproduce the problem and see if it still does if you think it would be helpful.

I am talking about me of course and not OP:

• I made a backup from BETA version 7.5.0.
• I formatted the device and reinstalled Signal from the official site thus putting the STABLE version
• I tried to restore and was told that it could not be done because the backup was from a newer version. I said "okay" because I wasn't interested anyway and once I registered the new device I ended up with only one chat. The group, of which by the way I am the only administrator, was not there and if I tried to access it via link I was told I could not do it (it is a closed group where the admin has to approve users).
• I then uninstalled everything and put back version 7.5.0 BETA, restored the backup and all the chats came back.

If you think this behavior is not normal I can try again to uninstall the current Signal 7.5.1 and install Signal stable.

@skariko When you registered with the new device, that was with the same phone number and you used your Signal Pin after confirming the phone number?

Yes I only have one phone number and the PIN was correct.
Unfortunately I can't seem to replicate the problem with version 7.5.1 so I have absolutely no idea what might have happened but I hope OP has more information on his bug.

I'm sorry, this didn't happen on a device under my control so I cannot send any debuglog, and as said now that the group info was fetched everything is working fine. Re-registration happened with a correct PIN :)
