The issue is still persisting for me

I have this issue since a few days, though sadly I don't know when exactly it started. I don't know if it is related, but the presence updates seem wonky as well, and this started around the same time. The messages show fine in Element-Web, but Element Android needs to be force closed to see them. Using self hosted synapse in my case.

I've been having this same issue over the past few days. Both on element android and desktop on fedora.

Same issue

Same behavior, no updates on the matrix synapse server side, looks like the issue is on the client side.

Can confirm this is occurring on Android and not on desktop

Experiencing same issue on Android

Experiencing the same issue, messages are not syncing with the homeservers and need a full app refresh to fetch new messages.

Should F-Droid users avoid updating from 1.4.25 for now, to be on the safe side?

Aug 14 '22 20:08 opusforlife2

I have the same problem and I think it is also linked to #6823 where you cannot edit your own messages after sending. It's like the client isn't syncing correctly...

I did not find any suspicious logs in the rageshake :/. Will have a second look later.

Seeing this on Element Android (F-Droid, develop and main builds), but not on desktop.

Very annoying to converse with somebody then accidentally find out later there were other messages that I didn't see 🤦‍♂️😃

OK, I can repro:

Kill the app
Receive a message with a Push. the notification is displayed.
Start the app

With this scenario, the SyncThread is not started, so the app is not syncing to get new messages. If Push are received for new messages, they are ignored, since the app is in foreground.

Working on a fix right now.

The 'mark read' option in any push notification doesn't work either BTW, not sure if that would be covered by the fix for this

Still no sync after update. Ensure SyncThread is started when the app is launched after a Push has been received. (#6884)

I haven't had this issue since updating to 1.4.34, are you sure you're on the correct version? Could also be a different issue or I've been lucky so far.

Same version. Desktop version shows new messages, Android app still silent at this moment.

@dm-msk can you send a rageshake please?

Aug 30 '22 13:08 bmarty

rageshake

i've sended rageshake with "ticket 6782" theme

Aug 30 '22 13:08 dm-msk

Thanks. I see lots of logs like this: /SYNC/SyncTask: Incremental sync request parsing, 0 room(s) 0 toDevice(s) in your rageshake, so I think there is an issue with your homeserver. You may want to do a clear cache from the app: Settings/General/Clear cache to try to fix this.

Aug 30 '22 14:08 bmarty

Yes, this has been fixed now for me since 1.4.34

Aug 30 '22 16:08 kylrth

Persists for me; I can see in debugging information that the SyncThread is idle. I have to restart the application. Also many times I don't get timely push notifications or voice calls. I'm using MIUI so I wonder if it's killing the thread, although I have it with all restrictions disabled.
