I have faced an issue, for many times. Some of my website users begin experiencing some type of ads when they are logged in and click on buttons making a server request but it happens rarely. It happens mainly after updating my website files and reopening it again. My host provider is Heroku. Why does this happen? How to prevent it? Does preventing this needs a higher tier? If it’s not from your side, could you explain why i am facing this strange ads? Please help me as soon as possible.
