hi, what apps / plugins can I use to get a proper 360 degree rendering of the M2P pictures, especially in android, Windows, Lightroom and Photoshop ?

Hello and good day Pa Cifista. Thank you for reaching out. I hope that you will get the best recommendation from our valued DJI co pilot with regards to these inquiry. Thank you.

I use https://pannellum.org/ for displaying the 360 images.

Photoshop has a built in 3D workspace for viewing and editing 3D panos.
Ricoh Theta software is a free viewer.
Android Google Photos itself supports viewing of them.

Free software from Microsoft for Windows:  https://www.microsoft.com/en-us/download/details.aspx?id=52459
Works fine at no cost.

It would be nice if you gave the name of the software instead of just a dead link.

Look for Microsoft ICE.
