RIGHT CONTROLLER FIX!!!!
Day one issue like everyone else. However, I took the battery cover off and fidgeted with the battery (after changing since the original seem to leak according to everyone else) and found that if I hold the battery down, it does not drop-off or quit working. Crumpled up a napkin and placed it on the lower part of the battery to hold in place, replaced the cover and BOOM! Back in business. Works great but this should not be the permanent solution. Hope everyone with this issue has the same luck as me. Now...back to Beat Saber! Good luck!
