Finally!

Two things:

One UI 7 is here in the UK for the S24 series. Great. I shall download it shortly.

The other: I could not open the app. I received an error message (-10) or something similar. Why couldn't I open the app? 

But I've updated and it now works. Before I uninstall and still didn't work at the time. 

Thanks.

@Jammy97  Hope you enjoy  One UI 7. Thre was a issue at samsung's end which 

has now been sorted. In the event of any problems try clearing the cache and Data of the app.

Thanks, I hope I will. It's a massive update in size.

I did all that: rebooting, turning it on and off, installing/uninstalling. I wiped the cache. Nothing. But I'm glad it works now.
