I would like to also confirm that i’m having the same issue as @keithrowley
When upgrading from version 7.6 to version 7.7.1 the transdirect shipping tab does not appear in the woocommerce settings, not does the shipping calculator appear in the cart. I then had to roll back the plugin to 7.5 and it is working correctly.
This rollback kept everything working, but then wordpress updated automatically (5.9.1 to 5.9.2) and now the transdirect plugin is causing a critical error when saving or editing a product. This is with the combination of wordpress v5.9.2 and Transdirect 7.5. It was working fine until I updated wordpress from the previous version.
The above comments lists two separate issues. I have completed a contact form on the TransDirect website also documenting this. I would like to have both fixed if possible. I would ideally like to run the latest version of wordpress also.
@transdirect can you please share an email address of which we can reach you?
