I clicked on the update link without thinking (Huawei tablet, Android 9).
EN10 is working reasonably well apart from being slow, the only other problems have been a lot of note conflicts (does it autosave?) and the simplify formatting button is missing (which is a considerable nuisance).
I also have a Samsung galaxy note 8 which I have not allowed to update from Android 8 because recording phone calls is very important to me (I use Cube ACR). The note 8 is still running EN8.13.3 successfully (no red bar) and thankfully the simplify formatting button is still there.
