WARNING! Open Beta releases are for competent and experienced users since they may not always be stable and are for the purposes of testing and reporting to OnePlus to help them develop future stock firmware and features. By installing this Open Beta, you accept the potential risks. Once on the Open Beta pathway you will no longer receive the regular OnePlus, Official Stable OTA's and you will need to completely wipe your phone before attempting to return to Official Stable OnePlus stock firmware.
This explains the Open Beta schedule and how to report bugs and issues...

Competent and experienced users of the OnePlus 6 can use a, "roll-back", firmware in Local upgrade to go back to Android Oreo and then upgrade to the latest stock, stable, OnePlus firmware for Pie. See...

There are also, numerous videos covering, "roll-back", on YouTube
(If you have any questions regarding the use of the, "roll-back", firmware, please ask them on the xda developers forum and do not clog up the Open Beta thread. This, "roll-back", firmware is not compatible with the 6T or McLaren. )
If you have the McLaren OnePlus 6T you, "may", lose the McLaren Warp Charge animation/facility by flashing this Beta firmware.
