Hello,
For the past few days I`m trying to register my windows 8.1 Phone as developer Phone to test an app that i`m working on. I use the windows Phone developer registration (8.1) tool as indicated in:
https://docs.microsoft.com/en-us/previous-versions/windows/apps/ff769508(v=vs.105)
When i enter my credentials (i checked 100 times if they are correct, they are). The status tells me: Error logging into the windows Phone dev center. Check your microsoft account credentials and try again. My developer account is active and my Phone is
screen-unlocked. I also can enter the dev center on my pc and phone
The Phone os is: 8.10.14226.359
Model=NOKIA Lumia 925
PC os=windows 10, with all the latest updates
Can anyone please help me try to understand why this is not working? is the windows Phone 8.1 development not supported anymore?
