Forum Discussion
I believe I have found the solution
Go to this link:
https://www.ea.com/games/battlefield/battlefield-2042/modes-hub/battlefield-portal
Sign in if you aren't already (This is important, if you don't sign in before you do the next steps that's what triggers the login looping).
Look at the top where there are directories for different things regarding BF2042 (This is different for mobile, tap the two lines next to the BATTLEFIELD 2042 text) and find "Battlefield portal", then hover over it.
Click on browse experiences and it might take a second to load (so might your experiences you have made or saved), then you should be able to use the editor like before.
This is what worked for me, I'm unsure if this will work with everyone, but I'll check up on this forum for a little while to see if anyone has anymore issues and mark as the solution if it works.
Good luck No-Pats!
