Android Client connects to Account but seems not to fully replicate

I’ve startet a new Account with Jami under W11. Checked functions with a friend. Everything fine.
We created a group, which is working fine too.

Then installed Jami on an Android 15 device with lastest updates:
Coupled device via QR and main account password which worked so far.

I got somehow connected:


The unsername of my friend is shown twice.
When i click on one of it, jami offers to download the conversation but nothing happened.
Searching for the group does not deliver anything.

It seems like the replication is somewhat stuck.

Thankful for any hints!

Please add yourself to your contacts/conversation list. Please click/tap “Start audio call” or click/tap “Start video call” with yourself between your devices to first test. If this works, please click/tap “Start audio call” or click/tap “Start video call” with your friend and see if the list refreshes. If possible, please ensure that both your Windows 11 and Android devices with Jami are online at the same time. Thank you
