Unwanted redirect on mobile?

Hello!

On this site my gf has two landing pages…

1. MAIN: https://eliatalleres.com/landingpage/elia-talleres-terapias-un-espacio-de-aprendizaje-y-de-sanacion-del-alma/

Available through the domain

2. Sub: https://eliatalleres.com/landingpage/terapias/

Available using sub-domain “terapias.domain..” or “..domain/terapias” but problem is… for some reasong when accessing via mobile (I have samsung android and she has iphone/safari), we are both redirected to the main site.

I’ve already looked for redirects and disabled any mobile plugins…

Thanks!
