Same here. 8.10 non beta, android 7.2, Moto X Play XT 1562
The app starts more or less as usual but every single note takes 15-20 seconds to show up! For me it started not earlier than YESTERDAY.
Right after the search hiatus. Simply astonishing! I'll tell you what. You're going straight the Windows Phone route. I'd let your employers sit on a new release for a month, and then the CEO for a week before even thinking about pushing a new release to the store.
Edit:
Going back as little as to 8.9.1 seems to be doing the trick.
