It is not to convince, as Firebase Panel works for all the new apps still. Due to some issues, Firebase panel stopped sending push to the apps using previous google-service.json files.

As always, we want to let you know that PushAdmin is an optional service, which users may or may not subscribe for, as per their convenience.

We are still trying to put our best for the services, despite the majority of users not supporting us by purchasing Genuine Editions, they rely on Pirated Copies, and just keep asking for Free Support.

Dear User,
We also have noticed the same issue. However, we also noticed there were some changes in google-services.json if we download it again. We tried to create the same app again using new google-services.json file and it worked perfectly. You can try your hands for this things.

As logically you might understand, the app is compiled, it was sending notifications previously, we do not control the apps, it suddenly stopped working. It is an issue arising through Firebase Panel itself, we have put our efforts in order to get it easy for all of our users. We're not asking for excuses, as it works fine if you try to create a new app with the same software.

Hope, you understand us. Assure you all of our best services and efforts to make it much more better.

Yes, AVG has removed the wrong behavior detection on our report, you should report it Samsung also. We are trying to notify as many anti-viruses as possible. Your contribution on the issue will be appreciated.

Dear User,
The simplest solution is to report your apps as False Positive to the AntiVirus teams,

We have reported for some apps, one of the screenshot is attached here:
