No, issue is still extant.
Browsers affected - Mozilla Firefox, and Google Chrome.
This may not be a copy/paste error. It may have to do with message length? I've noticed recent messages from others to myself have broken themselves down to several missives.
To reproduce - just write a message, copy it, send it (if you can), then try to send the same message to another by pasting it.
Really been affecting the messages to CEO's - but also had this problem communicating with Federation leaders today. Using Email for them in the interim.
Many thanks for your time and consideration,
