Hi,
I just bought a Huawei T10s tablet for my grandma. She can't operate a tablet, so I do it remotely. I have installed TeamViewer Host and Universal Add-on. I have added the device to my account. With each connection, the 'Privacy notice' message appears on the tablet screen and it is necessary to approve the connection:

If the screen is off, you need to turn it on and select 'Start now'. Otherwise connection is not possible. On older Lenovo and Sony devices, I don't get these messages and can connect without having to approve the connection.
Do you have an idea how to get around it?
