Kindle app keeps crashing on my iPad

I am using iOs15.5 on my iPad. I updated the kindle app on both my iPhone and on the iPad on the same day. Subsequently, the Kindle app then started crashing on both my iPhone and my iPad upon every attempt to open it. It’s not a problem with the devices, it’s a problem with the Kindle app. I have a rather large Kindle library and it is very highly annoying, because it is taking a very long time for Amazon to rectify this problem. Why not just role the app back back to the previous version? Is that possible? Over the years, I have seen updates on computers and software create all sorts of problems. This is among the most annoying. As it is said, If it’s not broken, then why fix it? I am referring to the update, with that idiom. However, in this case, why are they incapable of fixing it in reasonable time? Amazon has deep pockets; it is a very big corporation, surely they are capable of prioritizing this problem or hiring some help. It’s getting to be several weeks now; in that span they have issued only one Kindle update and it didn’t fix the problem. Normally, they are updating the app more frequently than that.
