App icon badge notification count is wrong.

[ara4n]

Steps to reproduce

The badge count on the icon is calculated by the server, not by the app, and so tends to be wrong.

Outcome

What did you expect?

Reliable app icon badge count

What happened instead?

We had #2066, but that was exacerbated by a synapse bug now fixed. The overall design problem from matrix-org/matrix-spec-proposals#4076 is still there though, and so the badge counts continue to be wrong...

I have suffered from this bug many times! I can accept that this is generally problematic, but going forward, is there any way to force reset the count from Synapse when this issue arises? Otherwise, could some reset cache button be added as an escape hatch as I believe resolves this is regular Element?

This wouldn't help as the app would still be using the count from Synapse I'm afraid.

@pixlwave But this is what I can't understand - I don't see this badge issue on any other client than Element X for iOS: even installing Element X on macOS results in the correct badge count. All regular Element clients also display it correctly. It's literally only Element X on my phone 🤷

Element iOS is using the badge number from Synapse until you open the app at which point it computes the badge locally as it has a copy of all the messages to use. Element X on the other hand is using Sliding Sync and with this, we don't (yet) have the code to fetch all of the necessary messages in order to do the computation locally.

Ah I see. Ok thanks, that makes more sense

This is super annoying and there seems to be nothing I can do besides disallow the badge.
