I’m having the same issue with my Ultra 2. Massive battery drain and also certain faces stuck in a low resolution state (earth, moon). Also having issues with certain watch faces not loading various complications. (Modular Ultra, solar and others) I’m also finding the Smart Stack is glitching horribly when accessed from these faces too. Double tap not working properly. General frame rate when using the watch is very low. The list goes on. Terrible, terrible update. I hope they fix it asap - until then do not update!
