Of course, FoodBook is compatible with any server-based website including AWS but we are unable to understand why you are facing this issue.
Maybe your server running an operation internally that removes the license again and again but have no idea what operation your server running internally that causes the issue. That’s why we mentioned changing the hosting to check the issue.
I wanted to inform you that I have tried setting up a fresh AWS lightsail instance with a fresh WordPress setup, but unfortunately, we are still facing the same issue. It keeps resetting the license key. Can not seem to find the root cause.
At this point, I would like to discuss further steps that we can take to troubleshoot this issue.
Thank you for your time and I look forward to your response.
