What operating system version number and eBay app version number do you have now?
If your operating system does not support the latest version of the eBay app and you cannot update your operating system, it should still be possible to use a mobile browser to go to ebay.com or ebay.co.uk and use eBay that way.
If eBay browser links are opening in the app automatically, iOS users should be able to tap and hold an eBay browser link and select "don't open in the app" to prevent that from happening. Android users need to go to the device Settings: Apps: eBay: Open by default: Open supported links and select "don't open in the app".
