Sorry, but how is this confusing? Images are synchronised between Google Drive and Google Photos. If you do something in one, it’s also done in the other. How hard is that to understand? Seems straightforward to me.
And let’s not forget that you have to turn the syncing feature on. It’s not as if Google forces you to sync. Surely if someone finds “the connection between these services is confusing” they could turn it off? Drive goes out of its way to make sure that you understand the impact of, say, deleting a file.
I like this feature because it makes working with photographs as files so much easier, and apps only have to be compatible with Drive to work effectively. They don’t need to know about Photos explicitly. As long as you can navigate to the Googe Photos folder in Drive, there are all your photographs carefully arranged by year and month.
Perhaps they’re telling the truth but I’m a suspicious old dog and I think this is more about Google trying to stop people getting their photographs out of the service by making it as inconvenient as possible. And what really annoys me is that I pay extra for additional Google storage.
Maybe Google should remember that Microsoft’s Office 365 Personal is GB£5.99 per month, comes with 1 TB OneDrive storage and Office apps for PC and mobile. That’s much better value than £2.49 per month for 200 GB and copycat apps.
