If you are in the beta version of minecraft, the fortune enchantment for the pickaxe doesn't work, its only for the beta.
There are many of these issues that say they have been resolved but they are NOT, and frankly its a little annoying.
sure I can just revert to 1.14 and have no problem, but none of my worlds would be playable because they are all on the beta version.
Resolved does not mean fixed. Look at the resolution: duplicate. The original issue, MCPE-67169, is still open.
