OMEMO messages sent from Monal are not decrypted

[foss-]

Describe the bug Sending an OMEMO message from Monal alpha or the current iOS beta are not decrypted in BeagleIM (or SiskinIM) for myself.

The recipient is able to decrypt just fine. But for my own encrypted messages sent from Monal I see Message decryption failed!

To Reproduce

1. open monal
2. open beagle both with same xmpp account
3. create a 1:1 chat with a contact
4. enable OMEMO
5. send encrypted message from monal alpha or beta

Expected behavior Messages should show and be decrypted in Beagle 1:1 chat view.

Current behavior Message decryption failed! message

Screenshots

Desktop:

• OS: macOS 10.15.7
• Version 4.1 (110)
  • Monal alpha / beta builds (links above)

Additional Info Talked to Monal devs and they mentioned that this could be the result of issues in regards to key transport element from a message stanza not supported or correctly implemented in Beagle / Siskin.

Did you test with any other XMPP clients than Beagle? Monal has been a non-functional heap of bugs since its inception and I would first go looking for bugs there.

Same messages decrypt as expected in converse js. Other clients worked as well, would have to check with non-Apple contacts which exact clients they use.
