Patreon Troubles? (Patreon)

I do not know what these problems are, but patreon does not allow me to send a mass message to everyone (by a General email) + I just see an error in the dialogs, my dialogs are all not read and I'm confused about what I read and what I didn't read

My patreon messages \ dialogs are completely broken and I don't know what to do о___о 

I will try to send everyone a message again, please wait

UPD - now I'm trying to send a message to many people, but NOT ALL messages are sent, and this is very stupid (I try to send individually to one user, and it doesn't always come either) х.х patreon writes that "a message is waiting to be sent" in many chats D:
