Hey @Kira_Do, thanks for reaching out!
In this case, access to an Education team is tied specifically to having verified education status (student or educator). So even if you upgrade to a Professional plan, it unfortunately won’t give you access to collaborate within that Education team.
If you still want to work together, here are a couple of options:
• The file could be moved to a free starter team, though this may come with some feature limitations.
• Or moved to a Professional team (If you decide to purchase the professional plan), where you can collaborate. Please note that editors on that team would require paid seats.
I know that’s a bit limiting, especially when you just want to help on a project. If you have flexibility with the team setup, moving the file is usually the easiest workaround.
Let me know if you have any further questions!
