Waiting this Might take awhile error

### Steps to reproduce

Element on android appears to be decrypting/receiving messages much slower than usual for my friend.
This appears to have been a result of me deleting the missed calls forms that appear after a call was attempted.

However I was able to reset my friends Element and once they have logged in again it appears to have solved the issue.
Since i have stopped deleting the missed call forms, there has been no such issues.
Both me and my friend's devices are Android, running the latest Element build from the Play store.

I have no idea what PR stands for so i said no.

### Outcome

#### What did you expect?
Delete the missed call forms without any issues

#### What happened instead?
Upon deletion it seems that my friends element client on their phone started showing "waiting for this message this may take awhile" messages.
