haha weird, so sa account mo lang pla ang issue? pero pag nag login ka using other account sa fb app mo ok naman? di kaya naka off and background data for FB?
pacheck sir sa FB settings.
Settings & privacy > Settings > Profile settings > Notification settings
then sa baba may Where you receive notification, make sure naka On.
Pa click mo sa Push may additional settings sa loob., make sure hindi naka on ang Mute
and you can check the other settings na...
