Unable to access default Book themes and fonts

Hi Everyone!

iPhone 14 (iOS 26.1)

After updating to Liquid Glass the default themes and fonts became inaccessible in the Book app. I haven’t deleted anything and all the default themes and fonts were already available and downloaded before the update.

Restarting the phone didn’t fix the issue and I have stable internet connection as well so I’m not sure how else to fix it. Could this be a bug or has anyone ideas on how to fix it?

Thanks in advance!
