Master output randomly goes into split (mix/cue) mode with Djay 2 and Mixtour for ipad

I am having an issue with Djay 2 using the Reloop Mixtour controller on an ipad (2018) (ios 11.3.1). The master output randomly goes into split mode with the mix on the left and cue on the right (the same on headphones too), usually after 45 minutes to an hour of mixing and when accessing the library. Obviously I do not want this happening during an actual gig. Is there a fix or a work around? Searching other places it seems that this issue has been occurring since at least 2013. Is Djay Pro immune to this bug?
