I live in low lands, altitude about 330’.This morning after I did my breakfast bolus, I got an All insulin delivery stopped. When I asked the pump to resume. I got “Altitude alarm, all deliveries stopped. Remove cartridge and reconnect cartridge and resume insulin,”

Tried multiple times but failed.

Tandem’s web site wouldn’t let me login. I did a hard shutdown. Had to replace the cartridge and set,restart the sensor and everything is good now.

Yeah, it took so long getting there I should’ve used a syringe.
