What’s the hardest geo-specific challenge to reproduce for your SAAS?

Hey folks — I’m building ProbeOps Horizon, a multi-geo browser that runs real in-region sessions so you can compare regions side-by-side.

Curious: what geo-specific issue wastes the most time for you?

• redirects / routing

• region pricing / currency / tax

• localization / content variants

• CDN / edge differences

• login / SSO behavior

Please share an example — I’ll suggest with how I’d approach reproducing and debugging it.
