Kindle app update no longer opens on my iphone or ipad
My app's updated 2 days ago, can't open the kindle app on my iphone 11 or my ipad, either they don't open at all or open and shut down right away. This is recent as I read daily off my ipad especially. Can't find how to fix it, have off-load said app, put back in. Shut the phone & pad off, rebooted etc, nothing is fixing this. This didn't happen before the app update. Seems to be the only one affected.
iPhone 11, iOS 15
