Stubborn as I am, I proceeded to factory reset the watch and tried creating some custom profiles again. Like @stolt, I started deleting some custom/old profiles (I assume that’s what’s causing the problem) and, after a while, I found myself stuck like before. Well, at least it’s a reproducible problem (I don’t know if it’s widespread) that Suunto might be able to fix
I’m on SA 6.8.13, fw Q1 2026.
