New app very slow to come up

The new app on my iPhone 8 is taking on average 14 seconds to come up. The old app was much faster.
I have a mesh network for WIFI which has great coverage and is very fast. All other items in my home are fast - cameras, Roku, Honeywell thermostat.
Interestingly, turning devices on via Alexa is instant.
Are others experiencing this?
