The – for me – very important function of offline notebooks in the new Evernote iPhone iOS app does not seem to work reliably at the moment: I have been waiting for days for the notebooks with about 7.000 notes in 40 notebooks to be loaded offline on the iPhone – they seem to stuck loading at 20-30 % – on all of my iPhones.
I have had a paid Evernote account for many years - I have to be able to rely on the service as my extended knowledge base.
