GrapheneOSuser74 in my case I have made secondary profile and I installed Google play store. when it asked me to creat an account I just skipped phone number window and the account was created without any problem.
That's because the IP address you had at the time did not appear on Google's blocklist and was not deemed suspicious by them.
GrapheneOSuser74 If you delete play store and reinstall it, Google play store will not allow you to skip phone number window during account creation.
No, it's because your IP address at the time was deemed suspicious, or something else you entered in the signup process was deemed suspicious, such as entering an obviously fake name, or a combination of those two.
