As is, periodically clearing cached website data may help. Hopefully, a future update will resolve the underlying problem.
In the meantime, Apple invites submission of comments and bug reports via its Product Feedback portal. For iPad and iPadOS:
Feedback - iPad - Apple
When submitting your report, ensure that you include your iPad model and installed version of iPadOS within the body of your report. Don't rely upon the pick-list alone - as this rarely includes the most recent models and versions.
Otherwise, you might consider seeking assistance directly from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, you can initiate and manage your support cases from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:
