I created an app with Glide and am on the pro plan. If I downgrade it back to the free tier, will I loose a portion of my users and data in the app? Thanks!
Free app limitations would very likely come into play — so your app would be limited to 500 rows (if you have more than 500 rows in your Pro app, I believe a free Glide app will just look at the first 500 rows it can find and ignore the rest).
