I believe that under the premium plan I would be able to work with private tables and AppSheet’s API to add, delete and modify values - is this correct? Thank you.
Private tables require PRO subscription plan, and API requires BUSINESS plan; see details on the pricing page: https://solutions.appsheet.com/pricing
@RezaRaoofi thanks. Above and beyond being disappointed, I feel like an idiot - I actually looked at that page but completely misinterpreted it. It could not have been clearer. Apologies for wasting your time.
