Making this note incase anyone else runs into this issue.
As is listed on the Airtable website, there is a limit of 50 interfaces per base and 50 pages per interface.
However, what is not made clear is what constitutes a "page". One might be mistaken to believe (understandably as I did) that "page" would be a "page" as is listed when you go to EDIT > "add page". (*sarcasm intended here)
However, when in one interface I had 22 pages, my "add page" option suddenly greyed out. (see attached screenshot for reference).
I tried to work with Airtable support on why this was happening, but they didn't seem to understand the issue and kept giving advice about record limits (which I am only using 3% of my 50,000 record limit and repetively explained to them that was not the issue I was asking about). But I won't comment on the unhelpful support beyond that.
To help all of you who may be facing this same frustratingly bizarre problem, I'll explain what I discovered on my own.
WHAT IS A "PAGE" Really: What counts as a page in the interface is not simply the list of pages when you go to "add page". Instead, any page that also uses multiple ways to view that page, counts as a page (see image).
Example: You have a Page for viewing contacts. Your default view might be "List View". Great that is one page. However, you may (inside that page) include different ways to view that same data. You perhaps select, Calendar view, and Grid as well.
Well, now you are apparently using 3 pages according to Airtable.
Be aware of this everyone, as it isn't explained anywhere and Airtable support, unfortunately, couldn't seem to understand when I explained it to them and I had to figure it out on my own through troubleshooting.
Peace 🙂
