AlwaysON Basic Availability Group configuring on Sql Server Standard 2016

Thanks Ahmed.
We have set up Primary Replica for backup while i was setting up AG.
I am new here, we have set up this way to take FULL backup through 3rd party backup software and TLog backup we set up through Ola script using Sql Agent.
Only issue when the database is in Synchronized state for Primary then i think it's not taking backup.
