I think I figured out the bug:
If the admin includes special characters in the global attribute term, your plugin sanitizes it and erroneously tries to match a term slug that doesn’t exist. For example, FoodBook sanitizes the label (Extra Chicken (+2)) which will result to (extra-chicken-2), and when compared to the variations available, that doesn’t exist. I believe your method of sanitizing needs to be reviewed.
Actually, we updated your plugin before confirming the error again. Then, we deactivated all plugins to isolate the issue and FoodBook still does not work. Can you please literally go in there and fix the issue for us?
The pricing was working properly and stopped working suddenly. If the price doesn’t update per variant, it renders the plugin useless.
Also, your “Add Feature” function doesn’t work. I updated the plugin to version 3.3 today, but that has no bearing on the aforementioned errors.
Is there any way you can actually login and fix this? We are losing a lot of time and the client is becoming increasingly impatient.
Thanks.
Thank you for your prompt reply. Can you refer to documentation regarding FoodBook’s “Add Features”? I am unfamiliar with this functionality.
Actually, the attribute in question is indeed global.
Thanks again.
Thank you for the prompt and thorough answers. The most important items are covered, and that’s what matters most. 
I agree that this is not getting enough attention and needs to be corrected IMMEDIATELY. Mobile compatibility is a MISSION CRITICAL feature and renders the plugin useless without it. Please correct this IMMEDIATELY. I am using the latest version of WordPress 5.5.3 and FoodBook version 2.7.0.
