I'm glad you like the Accelerometer feature (i especially like it in Cardboard mode, makes the game more immersive).
I have tested on my device and it is still working, please check again if the feature is toggled on : UI > Top Left side 3'rd button down . Try taping it once then rotate your device then tap again and rotate the device.
If nothing works then please send me info about your device and OS, maybe i can figure something out. (for privacy, you can place the info here or send the info to my email).
I hope this helps,
Cheers
