Some strange behaviour has started happening on a site.
On a desktop, the page looks fine. Likewise, if I go to Customize and view the site as a mobile or tablet, then it also looks okay. However, If I view the site on an actual mobile phone, the transparent top bar is no longer transparent but black with the site title written across it. The title was hidden and the logo appeared instead,
The site is https://purdylodge.co.uk/
Any thoughts please?
