If you target SDK < 31 then you’ll see reduced availability on the store. That means users with phones running Android higher than your maximum targeted version won’t be able to newly acquire it. Existing users are unaffected. If you target SDK < 33 then you need to update to SDK 33 because you won’t be able to make releases with the old target SDK anymore. (Existing bundles are fine). If you miss the deadline it doesn’t introduce further enforcement than that but it might mean if you had an urgent update you’d need to update the target SDK at that time. So sooner is better. Both have extensions available to Nov 1. Wear has different thresholds.
