Truecaller is blocking incoming calls on 2 separate LG handsets - V50 and a G8s. After originally believing it was a handset issue with the V50, I purchased a temp new phone Samsung A22 and also a new G8s. The Samsung works with Truecaller, but on the LG phones, it simply does not ring or show any indication of an incoming call. Started a week or so ago. I've spent over $1000. Truecaller, what is going on here?
