Hi, In the last few days, when using the Ionic CLI with “ionic serve” or to build an Android APK, I get the prompt to update the Ionic CLI from version 3.20.0 to 4.0.1. So far, I’ve answered “No” and have been successful to proceed.
See this ionic environment setup is actually very sensitive and if you update any thing ,it might not work after that . So,please continue selecting not to update unless you face any problems with your current ionic setup .
Im sorry which notification emails you are getting?
