FireBase Push Mass messages

[Dmitrii Efimov]

I don't understand a bit about the termination of support for the firebase API. Will this affect the usual sites that work through the endpoint 

https://developer.mozilla.org/en-US/docs/Web/API/PushSubscription/endpoint ?

I also started getting errors when sending push notifications:

The error looks like this: A valid push subscription endpoint should be specified in the URALS as such: https://fcm.googleapis.com/wp/dHIoDxE7Hdg:APA91bH1Zj0kNa ... Now the url is like this: https://fcm.googleapis.com/fcm/send/cvc76BaNkYA:APA91bECCHYCG1qgvrB1aAhS069XNpq1TcW8Pi[...]HCBcJOmgDPD2MuDrYXrNImNDtCHU_mBNPdoSWnwSqFqoCk-dYqPZ_BUu5yH
