Inventory import format for GS 7

Not intentionally in Sandbox. How would I know or even change it ?
What value does SB mode have and why would we want it ?

Cannot find any debugging. Using the latest Beta.

You maybe should contact the GarageSale support directly.

However, maybe it already helps to sign-in with Safari, restart GarageSale and try to fetch the token once again.
