Chainring shift alerts

My Edge 1040 and 1030 both alerted me when the next synchronized shift would change the chainring gear. This works with both Di2 and AXS. Riding with the 1050 on two rides, I have not received these alerts with my AXS shifter in synchronized mode. Is this not supported with the 1050 or is there a setting I need to make for this feature to work. It is super helpful.
