Thanks for trying this sort of things. Sorry, I don’t think it is the way to “solve” the problem.
If you press F5 too early, you won’t see the result. Even if it works, an average user won’t have the patience to do that all the time.
The issue prevents us from publishing our GPTs. If users have to suffer from this problem, they may assume our GPTs are lousy. Once your reputation is ruined, they may never come back to your GPTs again.
I also think that this is not the way to finally solve it. But it worked for me while I needed an urgent help in my work and thought that could help another ones in the same situation.
In my case this solution helped me. Of course it is not the final solution, but it allowed me to continue using GPT with a project. It is preferable to continuously press F5 than not be able to use GPT.
