I recently bought a dudu7 head unit, I am using sygic as my navigation app in pip mode. It all works perfectly except when switching from day to night mode, when the head unit switches to night mode, sygic doesn't switch with it, if I drag my finger over the map it does then switch over but its a pain to have to do that and then recentre the map whilst driving, and the same goes for switching back to light mode. I've tried all the day/night switching types and they all have the same problem. Do you have any ideas for this? I have the sygic pip turned off already. I have attached a link to a video of the issue. I have sygics day/night mode set to " follow system default"
