The URLs from which certain JavaScript files are loaded was changed following the 02/24/21 deployment. URLs for static assets typically include a cache-busting hash that changes on each deployment. This forces users' browsers to download the latest versions of those assets rather than using cached versions which may be stale.
Some of the updated URLs did not include a cache-busting hash. This would lead to errors being thrown when the user’s browser mixed JavaScript files from the previous deployment with those from the current deployment.
Affected users are advised to do a hard refresh on affected pages by pressing Command + Shift + R (Mac Chrome/Firefox), Command + Option + R (Mac Safari), or Control + Shift + R (Windows Chrome/Firefox).
The following UI widgets may not appear until the user does a hard refresh:
The configuration issue that resulted in un-hashed URLs was resolved in a hotfix. No further action required by users.
