Online Banking/ banking App

With standard bank changing your device leads to blocking features of other features on both online banking and your banking, they will advise that you need to wait 48 hrs before your app can normally work but in actual truth that not true. You will have to call in multiple time before you are through, only for a call to be loged as to why you cant make certain thing on your app.

My question is why is the new device affecting customers online banking when laptop/desktops are not new? we are advised to use online yet its not as helpful as they potray it to be, where does that leave us as clients especially with this pendemic, The aim is to frustrate customers.
