Kobo… again

Well, I fixed some of the issues with my kobo reading app for Windows. But only after I had deleted it and reinstalled it. And re-started my PC. Only then did the books I had bought started to show up in the app. Prior to that, they were lost from both the PC app and my phone.I still can’t work out how to find anything easily. It defaults to a search of the site when I want it to search my library.There is also no way to tag things yourself.My Kindle has a dozen categories: my star rating for GR reviews, the category, completed, etc. many titles are dual listed.And I can easily find a title.That makes me think twice about downloading on Kobo.
