S 100 Wall camera

Does anybody else have an issue reinstalling it on your Eufy App. Since day One its been nothing but a nightmare for me. to changing to easy passwards easier user names it take me freaking hours. Its ridicules. Now I cant get the damn thing to connect at all I am ready to punt it out the freaking door. Very unhapy customer. Its an older model but still what a joke wont scan my Qr Code. Why cant I just hook the thing up to my usb port on mt homebox 3 what could possibly be so hard about that. But no thats not a god damn option.
