Let me give you a quick update about my findings:
– Not being able to select variations is definitely tied to WP-Optimize in my case. (Screencast: https://lumiqy.de/WC8.5.1_issue_20240117.mp4)
– Items not being added to the cart after selecting a variation is caused my OMGF plugin in my case. (Screencast: https://lumiqy.de/OMGF_WC8.5.1_issue_20240117.mp4)
2 related issue but different causes. Both issues occur with Storefront as well, so I guess it is not related to Woodmart.
At least in my case. I’m now in contact with support of WooCommerce, WP-Optimize and OMGF. It seems WC 8.5.1 brought some changes which were probably not intended…
