On my jail broken paper white 4 I added a bunch of content from Blinkist recently and added them into two collections. When after restarting my kindle and tapping the sync content button they dont seem to appear. Nor can I see them if I do a search for them with the search bar.
They do show up fine on my iPhone on the kindle official app
Firmware 5.11.1
