I always use Night Mode as its easier on my ageing eyes.
The V1.8 Update has a problem with Night Mode.
When I turn it on it doesn't automatically change, I have to minimise/hide the app for it to switch to night mode. Also if I exit the App or switch to another route it always reverts to the Day Mode view!!
Even though it starts in day mode if I click Off and then go back and switch on it will automatically switch to Night Mode without having to exit/hide the app.
V1.7 seemed to remember the Night Mode setting but V1.8 doesn't. It always starts in day mode!!
Thank you for addressing this problem.
I made a ticket of this forum topic, we will look into this problem.
