Bingo

Is there a different way to do it? I tried this but after doing so, it won't recognize my cache drive so it wants me to reformat after starting the array back up, but its already BTRFS, and I have over 300GB on it, so I had to go back to Beta where it would recognize the cache drive. Is this something to do with 6.8.3 and cache drives compared to 6.9 which is causing it to make me have to format the cache again after the downgrade? I really just want to go back to stable but would like a way to do without having to move all my cache drive data out first :(

I am trying to downgrade back to the stable release "6.8.3" but when I go to 'Tool > Update OS' there is no option for me to go back to the Stable branch, I try to change the Branch 'Next' to 'Stable' but no option appears but just the previous 6.9-beta30 I was using. Please help, I regret using beta and just want to use stable :(
