If it’s not been showing at all then the most likely cause is that you’re no longer being paid by BACS.
When you look at your salary income, scroll to the bottom and if it say “Faster Payment” right at the bottom then that should clear it up. If you’re still not sure, just pop us a message in chat and we can double check it for you - especially if it is BACS and there’s a bug that is causing you to not be able to access it!
