13th Age Official Sheet not updating any values

I'm trying to use the official sheet and none of my players' characters' attacks, hits, or anything are updated when i change mods through the powers dropdowns, change weapons for melee/ranged, literally anything. I posted a topic earlier, but at the time I thought it was a more limited issue than it turned out to be.  Just updated to Pro to run this campaign and really frustrated. Is this a known issue and has anybody got past this problem?

Hi Kenneth P. Sorry to read that you've got troubles with the 13th Age sheet.  It seems like sheet workers (underlying javascript code which do most of the calculations on the sheet) are not working properly for you. This might be a very basic question but are you using Chrome or Firefox to play with Roll20, as these are the only officially supported browsers? And if so, are they up to date? Do you have any pluggins, add-ons etc. in your browser which could interfere with Roll20 that you could deactivate temporarily to retry?
