I have been working with Trello, using the free version. I haven't used it very often. Now the system is asking me to switch to Atlassian, and somehow a problem has arisen and I can no longer access my boards. Does anyone have any idea what might have gone wrong?
Have you tried recovering your account https://support.atlassian.com/trello/docs/recovering-your-trello-account/
It sounds like you’re running into the recent Trello → Atlassian account migration issue. When Trello asks you to “switch to Atlassian,” it means your old Trello login needs to be converted into an Atlassian account before you can access your boards again.
Here are the most common causes and how to fix them:
1. You may be logging in with the wrong email
Trello sometimes shows a different email during migration. Make sure you log in using the exact email you originally used for Trello.
2. You need to complete the Atlassian account setup
