"Your chat backup is out of sync" notification always present

[wavexx]

Steps to reproduce

Using element 0.4.14 on android 13.
Cleared storage/cache, then:

• logged in (matrix org)
• verified using the recovery key: "your device is verified"
• immediately afterwards I get the popup "enter your recovery key" (your chat backup is out of sync)
• I tap on it, enter the same recovery key again, hit confirm
• Confirm button spins, then stays disabled, nothing happens
• Try to go back: "enter your recovery key" popup still present (and visible at each restart of the app)

The recovery key is clearly valid, since verification after login works without issues. However, the "chat backup is out of sync" never goes away.

After closing/restarting the app, If I go manually go through the chat backup -> enter recovery key, the behavior is slightly different but results in the same:

• start element x
• see "enter recovery key" popup
• go through settings -> chat backup -> enter recovery key
• enter recovery key, hit continue
• continue spins, dismisses the page and goes back to "chat backup" settings
• red dot still present, indicating the backup is out of sync

Outcome

What did you expect?

After entering the recovery key, "your char backup is out of sync" notification goes away.

What happened instead?

Confirm recovery key button spins, nothing happens, backup stays out of sync at every start despite key being valid.

Noticed the "occasional" label after a while: note that this has 100% reproducibility for me, on all versions of element-x including current 0.7.0 (more reports on the same on the closed #2098 which is still getting reports). I've submitted multiple bug reports with logs directly from element-x on each version.
