hey there renatascherer, thanks for reaching out about your Oculus Go! As it was discontinued, we no longer support Oculus Go through sales or the store. Oculus no longer accepts new Oculus Go apps or app updates into the store as of Dec 4, 2020 so theres a good chance that the app is no longer supported on that device. Currently, we offer support for Rift S and Quest and Quest 2.
Hello, Do not know if it helps, you could try to use Web Browser in Go to see 360 photos on a web sites (with HTML page using WebVR markup). You could search for examples in the Internet.
Also you could run a web server on almost any device like local PC or smartphone and connect Go to it.
