Tide app freezes on welcome/splash screen



I’ve checked other answers and they don’t seem to apply (or at least the fixes they suggest do not work for me).

I’m trying to open an account.
I’ve installed the app on a OnePlus 6T. The app opens and displays a blue background, white circle and the words “Smart Business Banking”. It never gets further than this.

I have cleared the cache, cleared data and uninstalled and reinstalled the app several times but having no joy.
Currently with Cashplus and their app is rarely even working correctly so desperate to jump ship!
