Hey hey,
We are experiencing the same exact behaviour. It definitely seems, as if the updated App via Live Deploy is not built with the Production Flag “–prod” which usually guarantees a good performance on App Start and in-App-Navigation.
In our case, the Live Deploy feature is not usable in this fashion since we cannot justify these huge loading times in front of our customers.
So either we are forgetting some setting in Ionic Pro / our config.xml which leads to this live-deployed debug-build or we were not properly informed about this behaviour.
In any case, I am VERY much looking forward to an answer by the Ionic Team concerning this Issue.
Thank you.
