When playing from a recording which is still recording, time don't get increased.
Example:
Recording is 10min long when you start playing it, you can't watch it longer than 10min as it stops after the 10min what was recorded when you started the playback.
Then back to the recording list and start playing it again, recording is now 20min long and you can continue from the last point, but again you can't play it longer than 10min (total recording at this time is 20min and you did continue to watch from 10min) and again you need to restart playing it if you want to see next 10min of the recording.
Recovered 5.2.015 (not working as it should, same behavior) then changed to 5.1.033 which is working as it should. While watching recording time is increased all the time when recording is on. So, something has happened between those two versions.

Heard that the same issue is at least with the VU+ Solo SE
