Mail practically unusable after 18.2 - is it possible to revert update?

The iOS 18.2 update has now caused me to miss several important emails. The extra steps needed to find messages is a disaster. I have used Apple Mail for many years but for the first time I am now looking for an alternative.

Is it possible to configure Apple Mail to not use the categories introduced in 18.2 or alternatively to roll back the update so that I can have a usable mail app again.

EDITED to ADD

Thanks to Macrumors I have found that you can indeed turn off the Category view by tapping on the three dots in top right and selecting List View. It is a bit of a nuisance as doing it in All mail does not apply to all accounts and you have to apply the change individually to all accounts in your app.

A thought for Apple to ponder - just because you can do something, does not mean you should!
