2 year old iPad Pro 11” 4th Gen with IOS 18.5 (UK) Safari no longer functions properly

Over the last 3 to 6 months the functionality of Safari on my iPad seems to be reducing. For example, today I was trying to complete an on-line form and the send button wouldn’t work in Safari so had to use the Chrome app, where it did work. Other times it views pages differently to either in the Chrome App or on my laptop (Windows) to the point parts of the web page is is either missing or I can’t view due to the page size?

It seems to have gradually got worse over the last 3 to 6 months? I read that some Apple functionality would be lost due to the UK government’s argument with Apple - is this an example of this loss of functionality? Should we moving away from Apple in the UK?
