Android Studio应用定时通知无法正常触发问题求助

开发Android应用时遇到定时通知触发异常：要么设置后立即触发，要么完全不发送通知。目前已成功创建通知渠道，但通知始终无法按时触发。

逻辑流程：启动Service从JSON读取数据（此环节正常），校验处理后调用setScheduleForINI(separateTime(iniTime), remTime)方法，其中iniTime为通知触发时间（HH:MM格式），remTime为通知间隔（分钟格式）。

通知创建逻辑 #

class NotificationReceiver : BroadcastReceiver() {
    private val logShow = LogShow()

    companion object{
        private const val NOTIFICATION_ID = 1
        private const val CHANNEL_ID = "SonogiaAlarmChannel"
    }

    @RequiresApi(Build.VERSION_CODES.TIRAMISU)
    override fun onReceive(context: Context, intent: Intent) {
        iniNotification(context)
        val stop = intent?.getStringExtra("A dormir")
        if (stop == "A dormir"){
            logShow.logShowMsg("NotificationReceiver", "Repeticion detenida")
            Toast.makeText(context, "Buenas noches", Toast.LENGTH_SHORT).show()
        }
    }

    @RequiresApi(Build.VERSION_CODES.TIRAMISU)
    private fun iniNotification(context: Context) {
        val iniRemoteViews = RemoteViews(context.packageName, R.layout.notification_layout)
        iniRemoteViews.setOnClickPendingIntent(
            R.id.cancel_button,
            PendingIntent.getBroadcast(
                context, 0,
                Intent(context, NotificationReceiver::class.java).putExtra("action", "cancel_rem"),
                PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE
            )
        )
        val pendingIntent = PendingIntent.getBroadcast(
            context, 0,
            Intent(context, NotificationReceiver::class.java).putExtra("A dormir", "A dormir"),
            PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE
        )
        val iniNotification = NotificationCompat.Builder(context, CHANNEL_ID)
            .setContentTitle("Buenas noches")
            .setContentText("Ha llegado la hora de dormir, te deseamos dulces sueños. Att: Sonogia")
            .setSmallIcon(R.mipmap.ic_launcher_round)
            .setCustomContentView(iniRemoteViews)
            .addAction(0, "A dormir", pendingIntent)
        val manager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
        manager.notify(NOTIFICATION_ID, iniNotification)
        logShow.logShowMsg("NotificationReceiver", "IniNotification enviada")
    }
}

已尝试使用setExact等多种AlarmManager方法，调整执行逻辑，前置的JSON读取、参数解析流程均正常，但通知仍无法按时触发，请求协助排查问题。
