Hi, I don’t seem to be able to generate new access tokens using my refresh token. My refresh token seems to have expired? I thought refresh tokens weren’t meant to expire?

I’m only using a sandbox account, so perhaps it’s related to that? Thanks

Hey CustardCream! 👋

We’ve recently updated how we authenticate and strengthened our validations here - so this might be a side-effect of those changes?

I’ve sent you a DM so we can go over your app details and explore this further together! ☺

Have a good one!
