Solve the problem: Action must be taken regarding your account. Proof of identity via phone number 

You need to take action on your Google account
Prove that you are not a robot
A new problem appears, which is verifying the account using the phone number
The reason for the problem, its solution, and the problem of adding your number
First, this problem appeared again in accounts that subscribed to Google On via the free trial period link
To avoid this problem, you must not transfer your subscription and do not subscribe through the trial period link to prove this
You will see that only accounts subscribed to through the free trial period have this problem. As for accounts subscribed legally by paying money, no problem occurs.
The suspicious activity that Google refers to is the free subscription link
I do not advise anyone to do any suspicious activity on the account after this update to avoid being permanently suspended
Regarding the phone number issue
When you enter your phone number into Google and it does not accept it, an error appears
1 Sorry, a problem occurred and the verification was not completed correctly
2 This phone number cannot be used to prove ownership
3 This number has reached the maximum limit to prove account ownership
These errors can be solved by changing the phone
You cannot solve this problem on the same phone
We also talk about important topics regarding this problem, and I am working to solve these problems and will update you with everything new
