If you "Resend" messages (can be done from the chat menu), will they arrive? Just interesting. This is not a fix of course, but may be helpful in such cases. Maybe you also have logs from DC iOS?

I just resend the message as described and yes, it worked! The iOS user now recieved the message.

You can use it every time when you suspect that a message is lost. It will be ignored by Delta Chat if it was received previously. Anyway if you have logs from DC iOS for the time when the messages were lost, they may help. But not sure as it may be a server side problem.

there is no way to reproduce this issue nor an actionable item therefore. might have been a temporary server hickup

if this happens again, please open a new issue with additional information.

thanms for helping ❤️
