Thanks, but I’m using Fly and the latest version 1.4.12 has “lost” the 360 photo so I’m looking for something on Android/Chromebook that will do it for me. The apps I’ve tried don’t offer the choice of ratio. It stores the 26 images but doesn’t stitch them together. I can easily downgrade to 1.4.8 which works but it set me off looking for a way to do them outside of the app and not on the standard Apple/Microsoft platforms.
I’ve tried Theta+ but can’t find any way to create a pano from images. There’s also a review on the app as store completing they’ve removed the edit function.
I’ve stitched images together with https://www.photopea.com/ previously, its free. But I don’t recall if it produces 360 degree images. Worth a look if your still searching.
