NatWest customers are facing significant difficulties accessing the banking app this morning. Users have reported being met with messages regarding the migration of Sainsbury’s Bank accounts, following NatWest's recent acquisition of Sainsbury's retail banking business. This acquisition includes a range of services such as credit cards, personal loans, and savings accounts.

The bank has yet to confirm the cause of the app issues. However, numerous customers have taken to social media to express their frustrations. One user stated, "My Sainsbury savings account is transferring to NatWest but I also have NatWest current and savings accounts. When I try and use my NatWest app the only option is a link to the transfer Hub and I cannot access my existing NatWest accounts."

Another customer echoed similar concerns, saying, "My banking app has been taken over by the Sainsbury's migration and I am unable to access my NatWest account. Please can you give me a time frame for when it will be fixed?"

A third user added, "I’ve logged into my NatWest app, I understand there’s a Sainsbury’s bank merge, but I’m a NatWest customer who can’t access my own account online either. I have to use the app to authenticate access. Please help."

Additionally, a fourth customer remarked, "Hi, I'm a NatWest customer and a Sainsbury's credit card holder? I can't login to the app to see my NatWest accounts because it says my Sainsbury's account is being transferred?!?"

The Mirror has reached out to NatWest for further comment on the situation. As customers await a resolution, many are left unable to access their accounts, raising concerns about the impact of the ongoing migration process.
