Seems to be back up again now - for me at least

Yup

Down again slow clap for the big companies

This is the best summary I could come up with:

Thousands of HSBC customers in the UK have reported that they are unable to access mobile banking.

Downdetector, which tracks websites, showed more than 4,100 people had reported the banking app on their device was not functioning.

The problem comes on Black Friday, a day when many people will be making purchases due to the discounts offered by retailers.

There are hundreds of social media posts from frustrated customers affected by the outage, but one common theme is a frustration that throughout the morning HSBC’s service status page has claimed mobile banking is “operating normally”.

The exact number of people affected is unclear, because users must have a reason to check their online banking app to know if it is working.

If you are reading this page and can’t see the form you will need to visit the mobile version of the BBC website to submit your question or comment or you can email us at HaveYourSay@bbc.co.uk.
