Help accessing wallet please in Status app on iphone

Hi, it's been a long time since I've done this so I'm hoping someone can assist me. My daughter was gifted some ethereum and had it in the Status app on her iphone. She'd previousyl transferred some from there to her coinbase account to sell some when she needed to.

She's now gone in to the Status app and there's bugger all there, like $18 instead of upwards of a few thousand. She has her 12 word seed phrase. I can see that the wallet address still has a sizeable sum in it.

Of course, I don't want to screw this up but what's the process of accessing it again via the Status app, or perhaps another app? I though that we could simply enter the wallet address, followed by the seed phrase and boom, back in again. As i said, it's been quite some time since I've done this so any help would be appreciated.

Many thanks in advance.
