Hello, I have AT&T and now eSim from TMobile. It's going pretty well for the test trial, until I was on a call today and replying to messages, and realized I could only send from my primary sim. You click the message options 3 dots in the upper right and (while on call) you can not select which sim. But I hung up, and immediately was able to choose which sim to send from. Can anyone give insight into this, please? I replied to 5 messages while on a conf call, and now I've confused the heck out of everyone!
