Affected Version

0.16.0

Describe the Bug

When I open the same book (downloaded via OPDS on my Kobo running KOReader, X4, and Readest on iOS) any progress pushed from the X4 is not recognized by Readest or KOReader. However, if I push/pull between KOReader and Readest, it works as expected. Progress pushed from KOReader/Readest isn't recognized on the X4 consistently. If it is, it will only sync to the correct chapter, not the exact spot (as it does with Readest and KOReader)

If there are any logs or anything I can provide, I'm happy to. I just don't know how.

Steps to Reproduce

1. Open book on X4, read.
2. Push progress
3. Attempt to pull progress on KOReader

Or

1. Open book on KOReader, read.
2. Push progress
3. Attempt to pull progress on X4

Expected Behavior

Pushed and pulled data to sync between all devices and sync to exact spot.
