Hello,
1) Please provide temporary wp-admin access.
2) All the available sorting options you can find in Appearance > Customize > WooCommerce (Shop) > Product Catalog > Default product sorting.
By default, the sort order for your products is “Custom Ordering + Name”. Navigate to Products, then click Sorting. From this page, you can simply drag and drop the product rows to reorder them https://prnt.sc/owj42e
3) Go to Dashboard > Updates > click on Check again. Also, the plugin can be updated manually – https://xstore.helpscoutdocs.com/article/37-plugins-update
The core plugin update requires the theme update to the latest version before the plugin update.
Regards
