I occasionally get Adobe Digital Editions ePubs when Kindle format isn’t available. Removing and reloading the book in question showed the DeDRM Pre-Release seemed to do the trick for this book anyway.

However, any upgrade to an operating system comes with its own issues and it is not uncommon for devices to encounter problems. MacOS Big Sur is a highly anticipated upgrade for Mac computers, boasting many new features and improvements.
