I have just released version 2.12.3 of the plugin. This is mainly a bug fix for the issues with getting the reading status from the device. The updates are:
- Fix: Better handling when configuration of custom columns doesn't match existing columns.
- Fix: Validate selected profile when restoring/fetching reading status.
- Change: Only display tile related and the set related menu items for firmware before 4.4.0
- Change: Only show menu items that will might do something in current view.
These changes are in the recent beta versions.
Calibre will announce the availability of the update in the next hour or so. And if there are any issues, please report them here.
