Nano It's been discussed quite a few times on the forum, so the below is just my general copy/paste on the topic:
Unfortunately neither the SLR App nor DeoVR have been supported on the Oculus GO for quite some time. There are a number of reasons for this, but the primary reason is that the GO was deprecated by its own creator (Oculus/Meta/FB), which means that we are likewise unable to support the device.
There is no currently-supported version of either the SLR app or DeoVR for the GO, so any version that you may be using or that you may come across would be unsupported and would likely lack full functionality, for example with being unable to properly display our 190 degree fisheye SLR Originals scenes or being unable to sync interactive toys to scripts.
The only real suggestion I can offer would be to consider upgrading to a more recent, supported VR headset if and when you're in a position to, for example the Quest 2 or any PC-based headset. Many users, including myself. find the jump in visual quality & immersion when moving from a GO to a more recent VR device to be huge - and I say this as someone whose first headset myself was a GO (which I loved).
