I am having the exact problem on my Mac with Evernote (10.6.9). I can no longer use Evernote on my Mac, (Catalina 10.15.4,) and in desperation have to use my iPad which is most unsatisfactory and especially when I am paying as a premium subscriber. I can find no way to communicate with Evernote. Unfortunately I have not long renewed by subscription. Up until now I have sung the praises of Evernote and as a result many I know now use Evernote. However, until problems like this are solved and good communication is offered I will no longer recommend Evernote and will strongly reconsider finding an alternative when my subscription is up. I thought the problem was my computer and have wasted much frustrating time trying to solve the issue. I am so disappointed as up until recently I have found Evernote fantastic to use for so many things.
