Bedrock Beta - Fortune 3 not working

We have a netherite and a diamond pickaxe both with Fortune 3 enchantment and either of them seem to be working. Just dug up 4 diamond orr and got 4 diamonds. Just tested it on quartz and the same happens just one crystal. 

loving the beta - wish we had all the java extras too. 

 

all the best,
