Adding some components upon Web Viewer

Hey there!
I am using a web viewer in one of my projects. It is used to display google forms. I wanted to make a feature like after they submit the form, the user should be able to go back to the main screen either by clicking a button or automatically. Initially, I added a wait block and made the button appear. It worked a few times. But now after 3 months, the button does not appear. I don’t know why that is happening but in many parts of multiple projects that I have created, if I don’t open it and use it for at least a month or so, it starts lagging and creating issues that are nearly impossible to solve… I hope anyonee knows how to do this and I request the developerss of Thunkable to please do their best in fixing your interface.
Thanks,

Do you have a screenshot of the blocks or a project link you can share?
