i solved this problem with my go and sucessfuly installed SLR app
1 - download the last version apk app file that work on go given by themib :
2 - download the vrsideloader app from the bottom of this page: https://headjack.io/tutorial/sideload-install-app-apk-oculus-go-quest/ (you have to enter your email to get the link but you can use a tempory email like https://temp-mail.org if you don't want to put your email)
3 - from occulus headset go to setting -> storage -> select unknown sources -> delete any existing slr app
4 - connect your headset to your comuter, run the vrsideloader app , drag and drop the new app you've downloaded at step 1
5 - enjoy !
ps: you should have developer mode and usb debuggin on , but if you where using the slr app already befor they broke it everything should already be setup and you could just follow my step)
