Message senders are missing profile information in timeline

[marwing]

Steps to reproduce

1. Open room
2. Scroll up until you find a message for that you know that the author has a different display name and/or avatar and one or both are missing

Outcome

What did you expect?

What happened instead?

This seems to affect mostly one account (@daedric:aguiarvieira.pt), although in the first screenshot, another account is affected (@nacorid:vengeful.eu). According to this screenshot read receipts are also unaffected (see the RR from Nacorid).

In this one, daedric and Ricardo are the same account:

Here, the information was available and disappeared after syncing:

Replies are also affected, but mention bubbles apparently not:

• As can be seen from the clock in the screenshots (and the video) this happens all the time. Note that I'm UTC+2 if you're looking for these events in the logs.
• Missing profiles was sometimes happening before, but this definitely got way worse with 1.6.3 (maybe 1.6.2).
• ~This appears to only happen for events that were received before the app was last started. This means messages received while the app is open show the correct profile information until the app is restarted.~

Your phone model

iPhone 13 mini

Operating system version

iOS 17.4.1

Application version

1.6.3 (103)

Homeserver

Synapse 1.105.0 / Proxy 0.99.15

Will you send logs?

Yes

[marwing]

The last bullet point is incorrect. I just saw this happen for messages received while the app is open.

[stefanceriu]

@marwing I can no longer reproduce this although I did see it myself. Is it still a problem on your side?

[marwing]

I haven't noticed this in a while, and can't reproduce right now, so I guess this was fixed.

Nice, thanks! 👍
