A have a few cameras (7) mainly C210's. Also a small mixture of Kasa and Tap plugs on my system (Alexa). The Tapo app was working absolutely flawless for quite some time but I updated it a few days ago and I now have horrendous problems (2.8.8). Lockups, crashes unresponsive, blank screen at times and slowness to a stop. The APP IS TOTALLY BROKEN. The worst is when I view a camera and change to full screen followed by looking at a set of 4 I have set up. This brings out the worst issues and the APP IN NOW USELESS. I have uninstalled and re-installed the App and problems still persist. After reinstalling the APP my cameras & plugs appeared a 'new' appeared in the icons. When I check for recordings they are still there but as I navigate back on each camera I get a very short screen flash that twice I have managed to read before it disappeared. I was asking to switch on 2 step security. Once I managed to hold the screen before it disapeared but I could not do anything else. Even trying to send feedback within app can crash at times. Seriously broken!!!! I don't need two step security but I do need a working app as it was before TP-Link destroyed the working APP. Surely a company this 'good' can do better!!!!
