Oddly, the tags don't stick for me either. I assign the tags via the iOS clipper and when I check my Evernote, it carries the tag during the sync. But after the sync, tag info disappears from the iOS Evernote app and my Evernote for Mac app. I'm dumbfounded as to why this happens and I find that I always have to manually assign the tags all over again...
I completely agree with everybody here. I don't necessarily want to downgrade to an old version because the new updates are really helpful, but I just don't understand why the Notebook has to be JUST a list view. The folders were visually effective and made everything more accessible and organized. At least give us the option to switch from List view to Folder view! It's completely taxing to have to scroll through my many many notebooks to find what I'm looking for. Text is small and I just can't help feeling lost. Please bring the folder view back!!!!!!
