Often, Google Photos does not auto-stitch a series of photos.
On Android, you can use this app in stead: [Wayback] Bimostitch Panorama Stitcher – Android-apps op Google Play
I stitched the panorama photo in the Tweet below with it [Wayback/Archive].
You can find it back in this Google Photo’s album: [Wayback/Archive] photos.app.goo.gl/XgovxiK2CKJzdH4u7
Via [Wayback/Archive] Force panorama creation on Google Photos – Google Photos Community.
