Hi, @sjames95. Have you checked to see whether there are any software updates for your Z Fold4?
Additionally, you mentioned that you have cleared the cache. Please can you let me know whether you have also cleared the cache for the Google Play Store app?:
Hi @sjames95 , Check out Mitzzz999's post here: https://eu.community.samsung.com/t5/galaxy-z-fold-z-flip/halifax-banking-app-on-z-fold-4/m-p/6549846... . Looks like the latest version of the Halifax app that's just been released works.
