This feature https://simplero.canny.io/feature-requests/p/show-number-of-seats-left-on-priceproduct has just been implemented. Unfortunately it's now forced on, so if we restrict number of seats on a price it will always show. This was never my intention with that feature request, because in many cases (most actually I would guess) we don't want to show number of seats left.
So please either remove this function until it can have a toggle or give it at toggle now, so when we turn on restricted number of seats we can choose to show number of seats left or not.
The function also has a 10 min holding function, which is not good, if you're doing a webinar and the first 10 buyers get an extra bonus, then the first 10 visitors hold op the bonus seats, but maybe only 5 of them actually complete their purchases and then the 5 remaining seats are released again, while other fast buyers ended up not getting the bonus even though they purchased within the 10 first (and yes then I can do manual stuff, but then I can't show people if they're actually purchasing at the bonus price or not.
A really nice add on to the vitally important toggle would be to be able to start showing number of seats left, when it goes below a certain treshold, like for the last 3 seats. That would be really awesome.
