For the last few weeks i have been having this same problem. I havent used my gear vr since i got it in August 2017. The notification for the gear vr undocking issue comes up everytime i plug in my phone charger to my s8. Since this started my charger will not fast charge it only slow charges. Wtf has happened??? Im having to charge my phone a few times a day as its not getting proper charge & the charge i do get goes down rapidly, i am having to put it into maximum power saving everyday too.
To Oculus staff, please tell us when this will be fixed we need an update soon to avoid this annoying random message. I started to get this on my S8 after Oreo update.
We've discovered the problem and are working to fix it now. Please hang tight for a future update. Thanks.
