After upgrading all my devices (10 KP303s) to firmware 1.1.2 all the devices keep disappearing and reappearing in kasa app. Tried reseting and everything but still does it making kasa app useless.  However, everything works fine in tapo app.  Just thought I'd let you know in case anyone has same issue. I think its a problem on the back end server side.  Its not a connection issue as all devices  connected to wifi with excellent signal strength.  Checked router settings and all is good. Based on my research they are moving all kasa devices to tapo cloud. And latest firmware seems to break kasa app.  Would have been nice to have been warned so did waste so much time trying to 'fix' issue.
