2019 yz250f mapping

Hey all,

I had just picked up a 2019 yz250f. I downloaded the power tuner app and was able to get everything connected just fine. I have a handful of questions about using the app after not being able to find answers anywhere online.

In the mapping tab of the app, there is a down arrow and up arrow, one being receive map and the other send map. What is the difference?

Where online can I find and download maps other than the 3 that are initially downloaded?

I have the button on the handle bars to switch from map 1 and 2. Can you switch between the two while the bike is running?

If I have map 2 selected and the blue light is on and I shut the bike off, will it start back up in map2 when the bike starts?

thanks in advance!
