I used a prewritten code for hiding the title of my website on the first page https://support.wix.com/en/article/corvid-tutorial-hiding-an-element-on-certain-pages
It's working but on the mobile website the title disappeared on all pages when I navigate unless you refresh the page.
my webstite is www.adrienvanmelle.com
The bug is on all types of phone (I checked on at least four).
Thanks a lot for your help !!!
