Apple Watch sleep tracking is inaccurate after recent update

My apple watch updated 7-10 days ago and ever since then my sleep tracking seems to be off. For example this morning I got up at 5am and let the dog out. Went back to bed 5 minutes later and slept until 630. I know it wasn't a deep sleep again but I dozed on and off. It didn't capture any of that. Other days it has lost the first half of my sleep if I sleep from 1030pm to 2am or something and go to the bathroom. It shows me going to bed at 2 and loses the entire first half. I just started with the new update.

Similar results on my Ultra 2 since the watchOS 26 update.

Checking the time on my watch in the night, turning around after that and falling asleep right away is counted as being awake for 20-60min, for example.

watchOS 26.2 showed some improvements for two nights and then continued to give false readings.

My 3rd party sleep tracking, which uses the same data from the Health App, is showing more realistic results.

All effected users should all let Apple know about this issue by using the Feedback link, I have already submitted mine.
