Absolutely the worst why did you go and Screw something up that was working just fine I gave up after 4 attempts of downloading app. The ads have you all mixed up junk. I was using the old one all the time till you deleted it just the other day. Leave it alone if it works. Guess will have to find another video call app cause this one doesn't work at all
