Why always when you exit the Club finding page using the back button, it is so disturbing?

When you press the backward button after that, it will always take you back to the main menu...

Haven't heard of that one before.
There might be various ways around it.

If you're talking about the apps then clubs load in an embedded browser and the back button is the app button that returns you to the app.

The chess site is haunted 😝😝😝😝😝

Regarding the term 'clearing the browser cache' its really 'clearing the browsing data' ...
does this connect to the subject of this forum?
Yes.
If you clear the browsing data including to improve performance ...
then at least two other things happen.
The 'back button' will no longer work. Because there'll be nothing to go 'back' to.
Nor 'forward' to.
The other thing is that you're logged off the website by so clearing.
Which is maybe one of the reasons people have inhibitions about clearing the browsing data - but if you don't then the browser will get massively congested and then other negatives happen.
If you're on a website that doesn't require a login - then there isn't much problem.
You can open another tab or window and clear the browsing data.
And your first browser will be almost as it was.
You can refresh it too.
As a precaution you can copy its URL at the top before 'clearing' anything.
