i have same problem here, i try make new account for activate my new windows and register my device, i try fill phone number(my region phone code +62), but when i try next step, only show warning "We dont support that country code. Add an email instead.", after i try many times, it still have the same warning, and skip this step. after 4-5 hour, i try login again, my account was suspended, even i dont break the term of use or whatever your rules.
I try login, until request phone number step. And again ! when i fill phone number, it did not work, just show ***"TRY ANOTHER VERIFICATION METHOD, That verification method isnt working right now....."***etc. I read another post, mostly have some problem, suddenly suspended and cannot verify with phone number. even i try your solution, it still did not work ! Any another solution for my problem ?
