Can't get Gixen to stay Authorized

[awesomeitemsales]

I seem to be having lots of issues keeping my account authorized. I can't use Gixen at all right now. The app doesn't import anything from my watch list and wont even let me manually add items to bid on. Reauthorizing on the website seems to show it as authorized but as soon as I click import watchlist it says my authorization is expired. I don't have 2FA at the moment either so doesnt appear to be the cause.

How can I fix this?

Do you regularly change things on your Ebay account?

Like changing the password for instance, that appears to affect authorisation status.

I imagine that changing between two factor authorisation and standard authorisation might have a similar affect.
