I haven't done much testing because I have other problems in life, and the OP24 build is working fine now.
I just remember that the mounted Samba folder wasn't showing any of my Cryptomator and APFS Sparsebundle image folders, when the Samba drive was mounted as a RW user.
It was only showing some single files at the top level. I was able to create new folders and files.
Maybe it's related to the sizes of the files in the folders? I don't know.
It can be read but cannot be written to the exfat format of Samba of OpenWRT, when connect with the Mac Folder as the Samba client.
This is because Mac Folder and SAMBA rely on kmod fs exfat (this plug-in will be called when using exfat format, and this plug-in is maintained by the OpenWRT community) for poor compatibility, this issue does not relate to the GL firmware.
You cold, but looking around the forums for the past few weeks, many people aren't well versed in using SSH or OpenWRT in the first place. Or even the basic knowledge how to troubleshoot basic issues.
