@Wayne-TP Hello Wayne!
Yes, I know. One of the reasons is explained here: https://community.tp-link.com/en/smart-home/forum/topic/656802
My sister and me have a Tapo app with our mum's house devices because we go there sometimes and want to be able to disable cameras, sensors etc.
The other thing is that we both have devices in our house and we live with other people. If we share the account with these people we live with (we have to share accounts because shortcuts and more stuff can't be shared), they will be able to see and access all my mum's house stuff.
And we can't log out and log in every day in each account, we want to get the notifications from everywhere in case of an emergency
Does this make sense? I can make you a video explaining it better if you need it :)
Thanks
