Agree with GBE and cbn. Our development team is scratching their heads on why this is so different than every other integration. We were told to “have all of the pages open at once” but no system updates instantaneously, so this suggestion does not solve the issue at all. Downtime = lost revenue and frustration for potential and current customers. We now have to wake up in the middle of the night to deploy changes across our entire system as the best attempt at minimizing down time
