Can you provide a reproducible example / sample project ?

[Naveed-dev30]

@cedvdb you can reproduce it in new project

[cedvdb]

A sample is a repository or a snippet that lets other users try to reproduce your issue in about 10 seconds. This makes it more likely for your issue to be fixed.

[danagbemava-nc]

Hi @Naveed-dev30, you should contact firebase support. The plugin just sends the data along to the firebase backend. If it works for some countries but not for oman, then it is likely an issue on the firebase backend not the plugin.

Closing this as a duplicate of #11860
