After importing from Betterment, site won't load

I just imported from Betterment where I have a few accounts.  Betterment tends to have a LOT of transactions and usually I have to use the desktop software. I tried the web this time and now whenever I try to view my Betterment import, the screen loader just keeps spinning. I tried support and they didn't know what to do. Anyone else have this issue?  Any suggestions on how to fix it?
