Mapping a Polygon Comprising Above 100 Waypoints

This quotation is from Vico in a 2022 discussion about the 100 waypoint limit of DJI Go drones. " .You can do missions with more than 99 waypoints with all drones.
For older drones (the ones that use DJI Go as main app) which are limited to 99 waypoints in their firmware, Litchi will upload the first 99 waypoints, then once the drone has completed that mission, Litchi will upload the next 99 waypoints, etc until the end of your mission. For this to work, whenever Litchi uploads a mission, you need to be in signal range of the drone. Internet is not needed."

I just have two follow-up questions about the 100 waypoint limit.

  1. Does my Mavic 2 Pro, which uses DJI Go4, have this 100 waypoint limitation that Vico described as being a limitation of older DJI Go drones?
    . .

  2. If a waypoint mission is flown that has more than 100 waypoints, will the drone stop and hover in place at the 99th waypoint while the next 100 waypoints are uploaded from the RC controller’s signal, or will the drone RTH and await the loading of the next 100 waypoints only once back at the launch location?

  3. Finally, if there is NO signal connection between the RC and the drone when the drone reaches the 99th waypoint of a mission having more than 100 waypoints, will the drone RTH immediately, or will it simply hover in place until the battery drops to the level that a forced landing occurs? .
