For now the PWA is the best approach. (Actually it seems to be he best approach even when Adobe Build as working, but I digress.)
Yes, Adobe terminated the Build service last year. I imagine this was because of the reduced demand for it (see my PWA comment above.) While I need to complete some other bits first (Secwin 7 / NetTalk 12) I have finding a replacement for “Build” as a priority for this year.
There are a number of options;
a) Build was just an online service for Cordova - so it’s possible a local install of Cordova will meet our collective needs.
b) One of the alternative services potentially based, or not based on cordova, could be used.
It’s important to note that while NetTalk used Adobe Build (and by extension Cordova) it didn’t make use of any Cordova specific functionality. In other words a NetTalk app is “self contained” - database sync and so on is all handled by NetTalk. So switching the “packager” is not the biggest task - there’s no code in the app that changes.
