I downloaded your UB Sportsear for Magento 2 but I also noticed it has a ub_sportsgear_v1-0-0_beta.zip. How do I update from ub_sportsgear_qs_without_ext.zip to the beta version.
The file ub_sportsgear_v1-0-0_beta.zip you downloaded earlier is single theme for manual installation. As you’re new to UB SportsGear theme, I highly recommend you download the quickstart package ub_sportsgear_qs_without_ext.zip and proceed installation again, then you get a Magento instance with our theme plus sample content demo.
Please note this Quickstart package comes with no M2 extensions (If you purchase M2 Extension Bundle, you will be provided another Quickstart with full extensions built-in).
Please let me know if you need help further.
PS. You can find the guide for both manual installation and Quickstart installation here.
