Good day. How to fix bugs in the online store?

When you click on the link on the screen you need to click on Shop, how to make sure that Shop opens automatically when loading?

What needs to be done so that the picture is displayed (in production the picture is displayed)

If you add an item to the basket by clicking on the "add to basket" button, then the "add to basket" button will be disabled only in the next render.

If you go to the second page of the "see all" tab and then click on other tabs, the screen will be empty.

Thanks for the answers!) Happy New Year!
