Hi!
This thread doesn't seem to be very active, but I'll try anyway

Maybe someone is around and knows something.
My Plugin worked fine until a few days ago. Now it tells me "No card in the device" each time I want to sync the reading position, or load or send any metadata.
Calibre recognizes all my books, and it can send and delete books fine, other Plugins (like the Reading List Plugin) seem to be able to access the metadata just fine. Only the Pocketbook Collections Plugin can't seem to access it anymore. The metadata.calibre file is in the main folder of my e-reader.
Extract of the logging:

I'm using a Pocketbook Era with the latest firmware, Calibre 9.11, and Pocketbook Collections 1.2.6.
Attached you'll find the log.
Thank you in advance!
