The sender has blocked you from receiving this message because your device is unverified

I know you've been working on cross-signing issues, but seems I've encountered another one.

I had 2 clients in use that were working fine:

• Element Web on a laptop.
• Fractal on a Librem 5.

Connected to a Dendrite server.

I got a new laptop and set up Element Web again on this laptop.
I did not verify the session on first login, as I wanted to be sure that the browser data was persisting across reboots.
Second time I verified the session against Fractal (I think something hung the first time and it took 2 attempts to complete).

After verifying, all previous messages decrypted, but they all have a grey shield showing they can't be verified on this device.
Furthermore, new messages coming from a user who was previously verified are not decrypted (with the blocked message in the title), most of the time. It seems like maybe 1 in 10 messages do get decrypted (and possibly only when one of the other devices is online), but still show the grey shield.

On their end, they see my device as not verified. On my end, I see my device as verified in the settings. I also see their profile as fully verified, even though it won't verify the messages sent from those devices.

Example of a message getting decrypted among many that are not:

After rebooting, it appears that all those messages are getting decrypted again, but still show the grey shield on all of them.

But, still not decrypted when new messages arrive again.
