Hi,
thank you for your response. Unfortunately, I have to say that the issue hasn’t been resolved for me…
As you said, I have updated the plugin to the newest version. I am still able to add two products assigned to the same item to my cart. I can also book them one by one, and the availability is not syncing. Below you can find links to images with my configuration. If you like I can also share site URL, but I would like to do it in some private message.
