If you purchased your subscription in the mobile app, it's not possible to upgrade to a team account.

You can create a team for other people and invite members to it. If your team members already have personal accounts, they will need to cancel their current subscription first and wait for it to expire.

If you also want to be a team member, you will also need to cancel your current subscription first and wait for it to expire.

If you already have projects created and saved in the app, after creating or joining the team you will still be available to see and edit your projects. No worries 😊
