After fighting, for months, with lag issues with Evernote Version 10.10.5 (freezing completely for seconds-minutes and typing lagging behind for seconds-minutes), I FINALLY downloaded Evernote Legacy!
Omg! I finally can type in Evernote with ZERO lagging issues!
Why Evernote does not fix the current version, I do not know. I pay way too much for this service to have to deal with that!
