I see that all the time. I assume it's because the app is updated soon after the previous update. I don't sweat it.For months now, the Play Store has been screwed up. Each morning,, I check for updates. Apps that show up as being needed to be updated, has already been updated. It's very annoying. Does anyone else have this problem?
Each morning. I check MANAGE APPS. I get UPDATES AVAILABLE and a list of apps that need updating. Sometimes I get a list of 11 apps that claim to needed to update. When I click on the app, I see that the last update was performed 2 or 3 days earlier. There are only 2 or 3 that are needing to be updated. I'll try the suggestion about cleaning the cache and post the result.
Obviously, this is not a major problem but it is annoying.
I just turned off auto update. The reason I manually check is that I want to see what's being changed.
