Hello!

I have turned on "Lightning View" on my organization's Sandbox. When clikcing on the "Opportunity" tab (I have the NPSP installed) the browser gets stuck on a refresh loop perpetually. Interestingly if I close my browser and log in again, and click on the arrow and choose a specific opportuity or view, it loads just fine! I do not have this issue in the Classic View.

Any suggestions?
