It seems that there is a problem somewhere in the VoiceMessageAttachmentCacheManager that breaks rendering and playback for some of the voice messages. Restarting the app fixes it.

After more investigation this seems to be coming from cached completion handlers not being cleared and waiting for an operation that doesn't exist to finish. Need to find where original operation fails without clearing state.

I can't view the matrix message linked above, but I also have issues where people on Element iOS can't listen to my voice messages sent from Element Flatpak or Element Android. On the iOS end they look like:

I am able to listen to their messages just fine and listen to my own.
Is this the same issue?

Hi, thank you for reporting this. I can't be sure but it does indeed feel like the same problem. Hopefuly you won't see it anymore starting next release 🤞
