Groups created on mobile (Android) do not appear on Vector Linux desktop #56
Description
Bug description
Groups created or joined on Vector Android do not appear on Vector Linux (v0.3.3 and Nightly).
Steps to reproduce
- Create or join a group on Vector mobile (Android)
- Connect with the same npub on Vector Linux desktop (v0.3.3)
- The group does not appear in the Groups tab, even after adding multiple good relays and clearing cache.
Expected behavior
Groups should synchronize between mobile and desktop clients.
Environment
- Vector Android : latest version
- Vector Linux : v0.3.3 + attempted Nightly
- OS : Ubuntu 24.04
Additional information
- Contacts and DMs sync correctly
- Only groups are missing
- Adding relays (primal, damus, nos.lol, vibe.nostr.build, relayable.org, purplepag.es) does not solve the issue
- Clearing
~/.config/Vectordoes not help
This seems to be a known synchronization issue with kind 39000+ events.

Thanks for the issue!
This is known, it's currently a limitation in Marmot (MDK), only one device running Vector can receive invites and exist in a group at any given time, Multi-Device support is a planned feature for the MDK, which Vector uses: marmot-protocol/mdk#251
Once MDK has multi-device support, we will implement it. 🙏

This has been resolved as of v0.4.0, thanks for the Issue! @kerlannXmr 💚
Our latest Group Chat Protocol (Concord) replaces Marmot Protocol, with multi-device support natively and seamlessly supported.

Thank you team ! great work. 🙌
I just tried and I can find my PC groups on the mobile. Well done.
And the TOR service in the background is the icing on the cake that makes my private life happy.
Best wishes.🎉
