The biggest issue with Airtable for me and many of my clients is that I cannot restrict viewing some sensitive data for new users. Let’s say I have a base which is serving as a CRM and CMS at once. I can’t divide it into two even with Airtable Sync. So I’m adding a new content editor for the CMS tables only and he can see all the money data of my client. This is NOT good at all. I strongly believe that this feature is needed for most professional users of Airtable. The Airtable team has added recently an ability to set editing and deleting permissions — it’s great but it’s not enough at all. Because of this Airtable is a limited tool for me.
