Hi there! To clarify a bit of context: subscriptions to plans are based on teams, rather than on individual users. Your team (from the org plan here) is responsible for payment for all editors who have access to the team or your team files, regardless of whether that user belongs to another paid team or not — team billing happens independently from the other.
Thus, you would need here an editor licence in the Org if you would like to have ‘can edit access’.
Can you confirm if the Org is seeing the exclamation mark with a message that says "this person has a restricted account, as mentioned in this thread? If so, it is because you are currently set to viewer-restricted on the Org, which means you will not be able to edit any files until you are made an editor in the Org space.
In order for you to become an editor, you will need to reach out to an Org admin and have them upgrade you via the Admin settings → Members tab. I hope this helps!
