Redacted messages before 2023-07-26 appear unredacted

Steps to reproduce

Description of the problem

Following an old conversation in a private room, I've just discovered that every edited/redacted message in the timeline before 2023-07-26 appeared unredacted. They are still marked with (redacted) and showing all redacted versions correctly, but in timeline the original message appears instead of the last edited one. This affects all my rooms except the ones where there has been no recent activity (in timeline from myself). All redactions after the above-mentioned date are unaffected.

For me this is a high priority/impact bug, as it makes it almost impossible to follow up with old conversations in rooms with plenty of redactions.

How to reproduce

1. Be in a private room with recent activity and timeline reaching before 2023-07-26
2. Scroll back in timeline until a redacted message before 2023-07-26 is found
3. Inspect redactions by tapping on (redacted)
4. Compare last redacted version with what appears in timeline -> They differ!!

Outcome

What did you expect?

Redacted messages to appear with the last redacted version in timeline.

What happened instead?

The unredacted version of edited messages appears in timeline (before 2023-07-26).

Addendum

Noticed this issue a few days ago right after the update to element-android v1.65.

Never mind. It was some kind of a glitch...
After clearing the cache (Settings -› General -› Clear cache) it all went back to normal 👍
