what does premium actually do?
I haven’t looked into it that much – although by checking if I needed to have premium I could see some of the stuff. I think it allows a lot more analysis of diet, exporting files, more goal-setting ability and ad-free. But for pure recording roughly calories in v calories out, and a quick breakdown of protein/carb/fat/sugars, the free version does it fine.
I had a period of roughly a year of not entering any food and when I returned to it, although apps were listed as connected they weren’t, disconnect and reconnect did the trick.
Same for me I think, although it seemed that doing it from the desktop site worked, whereas I tried plenty of times through mfp/health/cyclemeter in iOS and that didn’t work.
