However I’m still getting the Invalid Request message when trying to log in to the app. I can still log in via the DuckDuckGo browser. Earlier today I did a fresh install of /e/OS 2.6.3 on the FP4 and I was getting the same issue with eBay on the previous install.
Same here, eBay nit working. What I did is create a light-app via Hermit (Hermit actually makes an app out of websites, really a cool app). That works.
@ronnz98 thank you for the prompt to revisit this.
I updated to /e/OS version 2.7 a few days ago and downloaded the eBay app a few minutes ago from the App Lounge. I was able to log in and search. I’ve not tested buying anything but being able to log in seems promising!
