Hello @Letti0,
It doesn't sound as though you have sent a large quantity of messages to the same person and even if this was the case, as I understand it if you gave it a rest over the weekend, this should have refreshed certainly by today. (If you send a large quantity of the same message to the same person over a short amount of time, the system may cap you to prevent spam like activity – however this doesn't sounds the case for the amount you have been sending).
I wonder, is anyone else experiencing this when sending direct messages here in the CC?
If you can try tomorrow sending another message, perhaps to a different person and report back that would be really useful.
Thanks for letting me know and speak to you soon.
Lizzie
