Im a bit confused about the best way to update vuforia and unity, I read somewhere today that 2018.2 is the only version that will allow updates to the very latest version.
I got the latest unity hub which is 1.2.0, this is how I am installing unity and then vuforia
if I install unity 2018.1.9f1 then vuforia 7.1.35 comes as default and it offers an update to 7.2.23 (see attached) if you click on vuforiaConfiguration twice (doesnt work first time).
if I download this update then run the installer it fails (see attached)
if I install unity 2018.2.14 then it comes with vuforia 7.5.20 which in my older scene (which until today worked fine on unity 2018.1.9f1 and vuforia 7.2.23) then it throws errors relating to custom/videoBackground and CloudErrorHandler (see attached)
If anyone could help that would be great, Ive spend the whole day installing different versions of things trying to get vuforia updated so It runs better on as many ARcore devices as possible (which the newer versions promise)
