My Oasis was acting wonky, very slow, and seemed to freeze today so I held the power button until it restarted. Unknown to me, that also triggered an update to 5.13.7 which is mostly just awful. Yes, it is more modern looking and I guess trendy looking but the prior version looked and worked fine even if it wasn't hip and trendy. And this new stupid thing only shows 5 books per page as opposed to the prior version showing 8 per page so it takes a LOT more page turns to go through all the books loaded into the device. I don't know if this is a total failure but it is close enough. Hate it. Hello Amazon. Hate it.
