Update in progress and not running app

Can confirm... Have the exact same problem.
I'm running
Version: 3.54.33.131643470
Runtime Version: 3.6.3.130862347
on the Oculus Go (which I hope is the most recent, as I have no possibility to check whats the most recent version...)
with current Unity 2018.3.6 and recent Oculus Integration 1.34

I tried quite a lot, like switching between different backend versions (mono, IL2CPP), different build targets (ARM64, armeabi-v7a) but it all ends in the same problem as described in the post above.

I have noticed another problem (maybe related?): the logcat of adb spits out the following, as you can see, libAudioPluginOculusSpatializer is not found (although I tried here quite a lot too):

Same error for me, updated four oculusGo, for some app working immediatly, for other message update in progress and doesnt run... After sometimes (oculus turned on) app works... I really don't understand why... I realy like if Oculus team was better than that... Easy for us to put some application Keys only... BUT Oculus team need to make a better product first !!! 

Exactly same error for me.  I have two Oculus Go, one works fine, but another doesn't.

After 30 minutes break, it start working...

I ran into this as well and restarting my Go fixed it.

Same for me, at the moment i've tried a lot of restart but nothing. Any Oculus developer here that can reply to this issue ? 

Just stumbled onto this problem. Anyone found any solution to this?  Oculus help? Dont ignore this issue, i dont have time or energy to deal with this BS again. I have time sensitive project that i need to deliver and now i randomly have this issue. I have made so many builds and never had a problem like this before. 

Just tried to use my oculus go for the first time in 6 months but have the wait for update thing. Ive waited 1.5hrs so far. Looks like its back in the cupboard for another 6 months and devo coz i just wasted $15 on a game. Should have called it an Oculus NoGo

You might wanna try a firmware update.
We had similar issues on the Quest. Oculus staff said it was a problem on their end and they fixed it.
After that, quest owners did a factory reset and got the newest firmware. Maybe oculus support needs to do a fix on their end for the go aswell?
