Google Unusual Traffic Error

Having recently updated my iOS to iOS14, I am no longer able to search via google when on 4G.

I have an iPhone XS Max, and prior to iOS14 I had no issues when searching.

I have also tried Chrome and Firefox, all of which give me the same error.

I am asked to complete a captcha puzzle, but this continuously loops.

This never happens when on WiFi, and I clear my history, cache and cookies on a daily basis.

This also does not happen on my iMac or on my MacBook, it seems to only affect my iPhone and only on 4G.

Does anybody have any thoughts?

Oh, this issue is present on my work iPhone (6s).
