Cannot connect to the *right* dropbox account

Thank you in advance for your help. I would like to connect my dropbox account to airtable. Airtable will not permit me to add my business account, only personal folders from my personal / business account. I am baffled. Why not? Is this restriction coming from dropbox?

I have the same problem as above and this is blocking me switching to Airtable, anybody have a solution or workaround ?
