What happened to Battery Usage (apps used) used in the Battery Usage App (opens in new tab)

Every since I've updated my watches (GW 8 classic, 2 Ultra's (2025), GW7, and GW6 classic) whenever I tap on the Battery Usage complication on my watch, it shows the time left, but when I tap on the Battery Usage I invariably get "No app usage". Anybody else getting this and is there a known fix/workaround? TIA
