New upgrade 15.1

Whilst a few reports of issues are seen, such as yours, widespread difficulties are not being seen in these Support Communities.

Having updated to iPadOS 15.1, you may find that a forced-restart of your iPad may be beneficial - as doing so will often resolve an isolated software issue:

• On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.

We are seeing many reports of issues with the FaceBook App under iPadOS 15.1 - which would suggest that the App needs to be updated to be fully compatible with iPadOS 15.1.

For Facebook, the workaround is to access the service using your chosen browser - such as Safari, Firefox or other.
