What happened? It doesn’t work any longer on Mac??

This used to be my go-to application for meeting notes. It was awesome and allowed me to freely shift between iPad, iMac, MacBook, and PC. Now the app on Mac OS X 10.11 (El Capitan) does NOT work!! I have attempted to contact Microsoft and even provided the error report. No response. I suspect Microsoft has forgotten that its Office applications were originally created for the Mac… I am going to give up and go to Evernote and won’t look back to OneNote again. There is no point using an application that doesn’t have appropriate support from the vendor. FYI: This OneNote update from May 7 2016 DOES work on the Mac OS X 10.10 (Yosemite) computers in my household. This is an El Capitan incompatibility issue. I can’t roll my iMac back to Yosemite as it’s brand spanking new (less than 2 weeks old). Thanks a lot Microsoft - NOT!
