4th gen iPad, wifi-only; latest version of the Logos Bible app...
I have a M'Cheyne reading plan (4 passages per day) using the NET Bible. My preferred Bible is ESV. Once I finish the 4th passage for the day (using "Mark Read"), the reading plan takes me to the first passage for the next day. The symptom of the bug is that if I use History at that point (long press) and then touch the ESV entry (usually 1 - 3 entries before the just-read reading plan entries), the app takes me to the ESV but it changes the location to the same passage as it was just on in the NET Bible (i.e. the next day's reading).
If, when I have the history list displayed, I press the "i" icon on the ESV entry to see the passage history within the ESV, it shows the right set of passages. I can press the top passage entry at that point to go to where I expect to end up. But it ought to take me to that location without having to drill down another level.
Hope this explanation is clear.
