thanks for posting that. I reckon that as I have a newish KF I'd be OK

so you think trust amazon when it says " compatible", as they would not say that to someone who had an old generation KF.

I am still experimenting with reading options. I found how to download .apk fiiles for any free app in the google store, and thus was able to sideload the Kobo reader app to KF, and use that for epubs. It needs an extra "import books" step after sideloading or retrieving from dropbox but then it is fine

but my method does not work for transferring paid apps from google store onto KF, so I could not use it for e.g. the moon+ reader pro app which amazon will not sell. They "sell" the free version only. As it happens I much prefer the Kobo app anyway. They "sell" a bunch of other free epub readers but they all show as not compatible with my KF

Sideloadiing via USB from calibre ( with auto- convert to AZW ) seems to work ok also.

is auto-convert also available via CC i.e. if I connect to calibre library via CC & want a book that is only there in epub, will it be converted & wirelessly sent to KF ?

PS retrieving from dropbox is a pain, I have my calibre library backed up to dropbox but trawling through the folder structure is not convenient. ( & amazon don't offer the dropbox app either, google do ).This is where I am thinking CC would be better, but does it need to talk to a running Calibre program, & not just to see a backup of the library database
