deleted spam messages still are shown

[Flexmaen]

Steps to reproduce

There was spam in some channels with sexual and violent content (#element-android:matrix.org and #tchncs:tchncs.de were affected).

Although it was deleted by an admin before I checked the phone

• it was still in the notification bar (text only)
• and even worse: when I clicked on the notification the images still were visible for a moment in the element app although they already were deleted hours ago.

Outcome

What did you expect?

You shouldn't see anything after it gets deleted by the admin.

What happened instead?

Sexual and violent content still popped up as image.

@Flexmaen, I have seen this many times. It appears to differ to homeserver synchronisation latency in that it's cached by the application. It's distrubing.

I just wanted to file the same issue.
It is not a thing between different homeservers. Here it happened on a self-hosted company instance, which doesn't federate with other servers at all. Use case here was: a colleague accidentally posted a password into the chat (with me) instead of the target application. He then deleted the message a couple of minutes later, but I could still see the password in the notification bar of my phone.
I am using "Element Classic" (latest version from the play store at the time writing this comment) on android 16 (Google Pixel 7).
