Hi Concerttom 👋 welcome to the community! Thank you for posting.
Sorry to hear about these issues with your Sky sports login issues, and difficulties watching online. There's a handy guide on our site 👉 How to use the sky sports app? | Virgin Media Help which helps with advice and support on watching sky sports via their app.
Would you be able to let us know if this is happening just via the app or also their site 👉 Watch Sky Sports - News, Live Sports, TV Shows | Sky Sports ?
Are both the iPad and iPhone up to date with both software and any app updates? (If not, please update them and let us know if the issue persists!)
If you can also please try; restarting the app, restarting the devices, and re-installing the app if needed.
Let us know how you get on and we can offer further support if needed! Wishing you all the best. 🌞
