Android Question Firebase does not return token

[JEG]

A complex Firebase project set up last year under B4a V6.00 worked without any problem

Using Erels Tutorial under B4a v.800 I have encountered the following issues;

1 Cannot get it to return a Token. Adding a sleep 30000 is of no help.

2 Loading the identical program into An Asus tablet and a Huawei (same as used under V6.00) and sending a message to SubscribeToTopic("general") the following happens;
The Asus to Huawei works
The Hauwei to Asus delivers the message to the Hauwei and not the Asus

Any suggestions

Issue of Asus not receiving messages resolved by going to >settings the >firebase app and clearing all data
