Anyone know if you change to BETA app can you change back if you don’t like it

I have changed but want to change back but can't find a way. It's a unmitigated disaster as I find the new format unusable on my iPhone. You can't find any of the information you want easily. There was nothing wrong with the old design at least in the front page you had all the information clearly laid out. I only use my phone so it may work better on a large screen. But on the phone the cards are way to big and bury what you need in endless flicking

It said when I switched that I could give feedback but even that's not possible. Waiting to contact support to see how I can revert. Really don't watch till you have to unless you have a massive screen!!!
