Yip. I had to redevelop a few apps that were reliant on this plugin. What I found worked very well as an interim solution was to make use of the Progressive Web Apps concept. You can use a plugin called Super PWA to get this sorted out in breeze.
Once you have a PWA installed on a device you can use an APK ‘sniffer’ to download the APK file to possibly use in the Play store. Not sure about Apple stuff though. Never had too much success there.

You can also use OneSignal to handle the push notifications to you apps. You’ll need a free account on their platform, and you can find the Worpress Plugin here: https://www.ads-software.com/plugins/onesignal-free-web-push-notifications/
Good luck!
