"Verify this session" dialogues don't appear in "other" sessions

[JOJ0]

Description

I just upgraded my Riot-Web Installation from 1.5.15 to 1.6.4

Cross-Signing does not seem to work

Steps to reproduce

• One session has been verified using the "Recovery Passphrase" already, running in browser Safari
• Log into Riot with new browser (eg. Chrome)
• "Verify this session" screen appears and waits that users connect to "other" compatible session (1.6.0+ or latest iOS in my case)
• Go to any other compatible riot-web session or riot-iOS session (eg: Safari session or iOS session)
• No qr-code screens and/or emoji-screens appear on the other sessions. The verification process appears not to be working
• Only the last resort solution "Use Recovery Passphrase" seems to be working.

I would expect that when I head over to another session, automatically the "verification qr-code, emoji screens appear and walk me through the cross-signing process"

Logs being sent: yes

When I log in with a new session B, I observe the following:

At the same time, on session A I observe:

upon clicking Verify on A I get the following on A:

Upon clicking Continue I get the following on A and B respectively:

This also happened to me once. On one device I got no prompt on any other device about cross-signing/device trust. Had to use the recovery passphrase but on all others it worked. So this issue seems to be quite random?

Where is this screenshot from?

When I log in to the "new" (to be verified) session in Chrome browser. It pops up in the very top-left of the browser window.

When I log in with a new session B, I observe the following:

Thanks for your pictures, this clarifies what to expect, In my case just nothing happens when opening any of my other sessions.

So both of those screenshots were from the same session and in the backwards order?
