I'm at the tail end of an EE upgrade (to v4) which includes the Store add-on (which per the changelog is EE4 compatible).
In testing, everything seems to be working fine EXCEPT that a logged in user can't view their orders. The area of the page where the code is supposed to render is blank.
Template code looks like this: https://d.pr/n/H607xq
Not sure what to try - docs are thin.
