No intellisense in typescript files debugging a device in Chrome Devtools


I am new to Ionic and have just started to build my first App. I am successfully debugging in Chrome Devtools no problem . I wondered if anyone has a solution for why I don’t get any intellisense in the typescript files (ok in .js files) when attaching devtools to device via inspect, but I do get full intellisense in all files when running the devtools from a localhost browser. It’s not a big issue as I can still watch variables and set breakpoints. I have got use to hovering on objects and getting the values directly.

Many thanks
