@jujuberry136 Thank you for starting this thread. It has been incredibly informational.
I had assumed it was a Mac OS issue being that I received an error when trying to access our account via web login using the iPad Safari browser.
For any users on the iPad that do not have the budget to upgrade each device, I was able to access Evernote through the web login using a different browser. There are several to try. We use Puffin.
