SOLVED - I found a solution using the well-known hacking technology to enter the appropriate code (without actually hacking anything!).
I have a domain name on 123-reg.co.uk and free web space on freehostingEU, with a web forwarding frame on 123-reg.co.uk to maintain my domain name in free space. To solve the problem of blocking the metadata meta tag on the site, go to website redirection settings somewhere like 123-reg.co.uk, where you can usually specify your meta title, meta script, meta author, etc. And enter the following code into one of the fields where you are allowed to enter some metadata for your page with a frame, for example, a meta-author and insert: -
your-author-name"><meta name="viewport" content="width=device-width, initial-scale=1.0,
which will then place the viewport code on the frame redirect page immediately after the meta-author. And it works because I just did it on 123-reg and it works great!
