Wonder if it possible 
Setting up Microsoft sign-up inside Bubble can be a bit tricky compared to Google. I’ve seen people struggle with redirect URLs and properly configuring Azure app registration. The key usually lies in matching the callback URL exactly and enabling the right permissions. Once the OAuth flow is set correctly, it behaves pretty reliably in both web and mobile.
Thanks! I have no issue with Microsoft on web. Created signup/login with both inside and outside the OAuth flow after running into “text to long for this field” on web. But thanks "@stevemarkocik! Then I know that I can work on mobile native!
