tldr is that you can hide the button that asks for payment and it says “purchase immich” instead of “purchase liscence”
+1 to everything you just said - I’ve been using Immich for a little less (370 days, thanks to the same button). It’s feature rich and rock solid.
Only thing I hope they add to the mobile app is the Years/Months/Days option, to make it easy to quickly group, then find, your photos. It’s the one thing that keeps me using my phone’s own Photos app (locally - no cloud sync).
