I have some encrypted files on my NAS (Netgear), I can access to my NAS by the LM file manager, I can mount drives, navigate and open all files.
BUT not cryptomator’s files. And that, by the file manager and double click on “masterkey.cryptomator” or by Cryptomator’s file explorer “other emplacement” (cryptomator don’t see any of mounted drive on the NAS)
