How to use Redwood - supplier (New)

Summary:

I can see redwood menu in 26A version but can't use it: when I search an existed supplier name, it didn't return any value..
Would anyone be able to tell WHAT needs to be done to make it function?

Also, does it have to do something to "enable" redwood function for each time version upgrade?

Version (include the version you are using, if applicable):
