Hello everyone,
Thanks for your patience on this one.
While this has been confirmed by WooCommerce as not intended, we have made the necessary changes in Cwicly to no longer rely on this specific package in 1.2.9.8. You should now be able to use 7.9.0 with the latest Cwicly update.
Thanks for your understanding and sorry for the inconvenience once again.
Cheers,
