I think I may have a solution to this problem.

If you’re buying or selling on eBay, you will no doubt get emails from them containing a link to the item you’re buying or selling.

When you do get an email with the link to your item, click on the item link and it will take you to your item.

As the eBay page opens, you will see the annoying message, ‘Update Required’

DO NOT click ‘EXIT’ button within the ‘Update’ box, but simply go back to your email message and click the same item link and you should be taken to your eBay item minus the ‘Update Required’ message.

It’s not a permanent fix, but it should give you access to the app.

Good luck !
