Multiple Phone Numbers in Big Sur Messages app on Mac
Before Big Sur, I used to be able to copy, say, 10 phone numbers, each separated by a comma, and past them into the Messages app... and then send a message to those 10 people.
In Big Sur when I do the same thing, the phone number either converts to one long string of 100 numbers, or (if I do a comma and space) wipes out all the numbers except the first one. This is absolutely repeatable -- the same things happens on my MacBook Pro, my iMac, and my MacMini.
The workaround I have been using, is to copy the numbers on my Mac, and then using the shared clipboard, I paste them into the Message app on my iPhone (which accepts the 10 phone numbers separated by a comma) and then I am able to type and send my message.
This workaround really shouldn't be necessary -- this use work perfectly well on the Message app (iMessage) in Catalina and previous versions. It was very handy feature to have. Why did it go away (or, more hopefully, is this a glitch that is unintended)?
