Issue with date pickers and look ups since Winter 20

Date pickers and lookups are taking - 10 to 15 seconds to render in API1, Skuid 11.2.6. Across the team, across all pages. Help please

Hi Ben, did you already see our announcement about potential performance issues in Winter’20?
The latest releases including a fix for the issue are available on our Skuid release page. As a reminder, Salesforce does NOT allow reverting back to prior versions of managed packages. Skuid always recommends installing new versions in a non-business critical sandbox environment to test all mission critical functionality before installing into a production environment. We also recommend that you update out of date themes after you upgraded.
