CUSTOMER SUPPORT????? ADMIN??? I want to upgrade plan and pay you money, but... no way to contact, re Mavic 3 Pro

Hi,
I have an old Mapper plan for years, which i used for mavic 2 pro.
Now I have mavic 3 Pro and I am out of luck using this plan any more. i see the problems described and I understand DJI issue - but info about support for Mavic 3 Pro is VERY inconsistent, like someone forgot to do updates in support files. Some notes say it works for M3Pro, some say it does not.

There is a mention from June 2025 that it works as Waypoints only. OK.
So, i try to export KMZ file (made for mavic 3 Enterprise - because M3 Pro is NOT included in drop-down drone list despite claim it is supported now!!!!!!) And when i try to export/convert KMZ - it tells me - i need to upgrade.
OK, so i click upgrade - and there are options. I click recommended option (modern drones/waypoints) - and again - it lists drones working with it, but NO Mavic 3 Pro is shown there.

So, before wasting my money, I would love to hear from sales or customer support, and know that my upgrade makes sense.

I mean, HELLO - is anybody home? no one to contact? Even for sales? Is the company still really active? I find it weird.
Please answer and address my worries - should i upgrade to modern drone waypoints system? Or it won't work for me?

Also, would be nice to see a more detailed info what will work in waypoints and what will not. It is quite foggy...
Thank you to anyone who can shine some light on this issue. Cheers!
