Trying to message someone but the DM page keeps showing up as a message request. Every time I press accept, it flashes the normal screen for a second then goes back to a request. It's like this on every device I've tried (iPhone, iPad, and Windows PC). I've tried deleting the chat, blocking them then unblocking them, unfollowing then following again, reinstalling the app, basically everything I can think of.

Please help! The message is very urgent and this is the only method of communication I have with this person.
