Apple Notes - won’t reinstall

I have my apps set to be put on the cloud when storage space is running low. I hadn’t used Notes for a while, so my phone put the app on the cloud. When I tried to use Notes again, it wouldn’t put the app back on my phone. It downloads about half of it then stops. After a minute or so, it just goes back to the cloud/arrow icon. After trying for a few weeks, it still won’t download/install.

(My notes are still in iCloud, thankfully. )

I tried deleting the app and trying from the beginning again but the same thing happens. It refuses to go past about 50% downloaded.

I’ve been trying now for a month, to no avail. Please help!

TIA
