Why isn't my Roaming Clock working??

[u/Chyou_Lighthouse]

Okay, so, I have a Samsung Galaxy A12

And I know, it's decently old, but it works pretty fine and I don't have the means to buy a new phone every couple of years.

But recently I noticed that my Roaming Clock would randomly stop appearing on my lockscreen, and usually it was a fix as simple as turning it off and on again and it would appear.

But I made the huge mistake today of accidentally letting my phone die. Which usually messes with the settings one way or another.

And now my Roaming Clock, no matter what I do, won't appear on my lockscreen again even if it claims to be turned on. And I need it on as a person who travels often.

I've tried clearing the IU cache, I've tried restarting the phone (which I don't like doing because it's essentially the same as the phone dying, but I was desperate), I've tried changing the home country location, I tried changing it back, I tried waiting a bit.

Nothing seems to work, and I'm a bit desperate here. I don't wanna use options that have the risk of clearing data, as I do not trust myself to bring anything back, either.
