I was recently tasked with building a PWA to escape the play stores. A vitally important feature was notifications for the messaging system. Hours of research trying to figure out how to deliver a notification through the PWA, even if the application was closed. Eventually I thought it wasn't going to be possible. But I remembered the HEY products were PWAs, and they had an email product. Surely that has the notification feature I'm trying to replicate? It's a paid service. ... no, I couldn't get their notifications to work, even though I enabled all of the proper settings. Crazy. However, when I was about to give up and abandon the entire project, I had one of those moments, and got it to work.
