Kindle Current Page Issue

Hey all! I’ve been using Libby for only 6 months but it’s been great with my kindle!

However, I use the kindle app on multiple devices and recently I noticed my Libby books no longer switch between devices. Usually, if I leave my kindle at home and open my kindle app on my computer, it ask something like “do you want to go to the most recently read page?” And if you click it it’ll jump my app to where I left off. Same when I switch back to my kindle.

Last few books though, this isn’t happening. Is this any issue now or anyone else noticing this?
