App Store shows open button instead of update
I have the application on my iPhone 5 and iPad mini 4. Today I updated it on my iPhone 5 via App Store but I can't update it on my iPad mini 4. I just see the open button.
I tried to reboot my iPad but it does not help.
Is there any way how I can update the app on my iPad exсept delete the app and install it again?
iOS version is 10.1.1 on both devices and same Apple ID.
iPad Mini, iOS 10.1.1
