Many thanks @scrambler – all fixed, and the tabs all work properly on mobile now as well 🙂
For my next problem with tab groups, the minimum height parameter doesn’t work (it didn’t work a month ago either, when I first started using tab groups).
In the help, the syntax for the minimum height parameter is described as both “page_min_height” and “pane_min_height” (so there’s a typo somewhere) but I have tried both variants and neither works 🙁
