Direct message to some users fails for one specific native mattermost user.
Steps to reproduce
Im a bit unsure of how to reproduce as this only happens to one user, not observed in any other user.
This user is not imported but natively created in mattermost.
Version and configuration in our setup:
version => ‘4.9.1’
‘EnablePostUsernameOverride’ => true,
‘ExperimentalGroupUnreadChannels’ => true,
Message successfully delivered between users.
My user consequently fails to send or receive DMs to and from specific users. (like they are on some block list) Chatting with the same users in public or private channels is not issue.
When I try to initiate DM to the affected users I only receive a “Retry - Cancel” message, and no chat history is loaded. When they send me messages they dont receive any errors and the conversation is added to the chat history but it never arrives.
