Playback is not working #2
Description
When the user presses "Playback Last Session", the display does not update for a long while after. Python appears to be retrieving the data quickly and entering the while loop used used to stream the data to the front end, but this data appears to never reach the front-end until well after the data on the back-end is completely sent. When it does reach the front-end, the playback is choppy and incomplete.
