1. On my Home page in the Header I have slightly darkened the background gradient to enphasise the white typing. This is fine on PCs, laptops and phones, but on the only tablet I have, an iPad 2018, the text in the H2 heading is white, but the telephone number is dark blue making it virtually invisible. In tablet mode in customise, the phone number is white.
2. I lost the two identical images in the Blog Post, but changed the one in the Blog page and sometimes the old image appears on mobile devices, but again always ok on previews.
