Slightly different install problem
I too have update issues. I'm not being asked for credentials, instead I am getting a notice the the Cookie5 app is corrupt and being told to delete it and reinstall it from the app store. I do this and the same message reappears.
I assume this will be fixed with the version 5.8.2 update so no need to respond to this post, just wanted to let you know about the different issue I am seeing.
If this continues I will let you know!
