I haven’t seen anybody report this, so I guess it is just me.
I made the mistake of allowing my fairly new SanDisk Clip Sport to update its firmware (I assume it is 1.22 now). Before the update the player would remember where I left off in an Audible audiobook when I turned the player on. After the update it no longer does that. Instead I get a brief yellow flash screen that says “no files found” then the main audiobook screen. From there I have to step through my book list to the book segment I was on, select that, and select resume.
So, the .pos file is there and working fine. But the player no longer remembers where I was when I first turn it on. Quite annoying. I’d go back to the firmware that came with the player if I could.
