For several months I've been unable to download software from the Play Store. It does not ask me for my credentials, and from all outward appearances it is successfully downloading the app; however, the download never finishes. I just checked my download speed using OOKLA SpeedTest, and it was 21.36 Mbps (it often is about 26 Mbps). So I don't think it is a speed issue. My App storage used is 0.88 GB; I have 1.95GB available. So I don't think it is a storage issue.
