With the many positive statements we have for PWAs, i wonder how Yappadappadoo is tackling the downsides of Progressive Web Apps?
Knowing that mobile devices, more often than not, has its own proprietory browser and could be an obstacle to reach the multi-browser capability should manufacturer choose to redesign their browser far from the current acceptable browser engine where PWA works best.
I see your point elycoinz and would like to add that currently, PWAs works best on Android-based browsers. It is only through this mobile device OS that some hardware feature of a device could be access with no issues (like cameras, calendars, location, etc.).
I'm pretty sure it would be a drag should the mobile device uses a non-native android browser.
I hope Yappadappadoo already have a team for this.
