My guess is technical reason drove decision not “Lolz, no more iOS 15”. Looking at our telemetry data, less then 1% of devices that run our B2B app are iOS 15 or older. If we ran into iOS 15 issue, we would lock them out as well.
It amazes me the money that brick and mortar businesses would spend to increase customers by a tenth of a percent, yet online businesses have no problem simply deciding that 1% of their clients are disposable. They would rather develop some new shiny feature that won't bring any new clients, than continue supporting a device that was sold new three years ago.
