So I’ve had this issue for a few betas now, but my friend who isn’t in on betas is seeing this as well. During a call, I can remove apps from the app switcher once. After that I’m not able to. The only work around I’ve found is to lock the phone and repeat the process. I asked Apple support but they said they don’t have this issue. I’ve already reported it several times in the bug app.
Both phones are X’s and on 11.2/11.2.5b
