Hi,
We tested our plugin in various environments. It works fine so far. If you find a problem, please tell us the environment you are using, like WP version, PHP version etc. We will definitely fix it if it is confirmed.
We also noticed that you left a one-star review on another booking plugin without good reasons. It seems that you are doing this deliberately. We don’t think it is a good idea.
We hope WordPress team can review this case and help us plugin developers live in a better review system.
Thanks.
BookingRobin Team
