DDJ-200/WeDJ/Galaxy pad splitter volume issue

I am having volume issues when enabling cue splitting on WeDJ on Android Galaxy Tab S3 pad. When I enable split output, the maximum volume drops substantially, I’ve tried different speakers etc but just goes so quiet even though volume is at maximum. Switch it back off and volume jumps straight back up. Doesn’t happen if I use my iPhone. I’ve tried everything but can’t get round it.
