Can you please provide more details as to why you can’t edit the teams:
Were your teams set from the last Guild Wars but they reset this week?
Did you try selecting a new team with their banner beneath the Guild Wars “Day #” and then exiting the menu? 3. Please send some screenshots through?
Yes, I have the teams from the last guild wars (being a relatively new player, didn’t understand about having different teams every day for bonuses). But I have better cards now, but can’t update. So I can play meaningfully for my guild, but it’s an annoying bug.
I tried (for various days) choosing new teams with their banner below various days and once I leave the edit screen I still have the same team chosen. I did try editing the one team that works, which did change my team, but on all the days. So the game won’t accept different teams, though I can edit those two teams.
I will work on screen shots and put them in a later answer.
