Suntrust Mobile banking down.

I have been able to log on to Suntrust mobile banking once since Friday. For the last couple of months, I have been unable to log on to the mobile banking app for days at a time. I would make a transfer in the morning. Then, I would try to log on that afternoon to pay a bill and nothing. I understand maintenance is needed. And many times that is done at night or early morning. But, the the times I have tried to log on are at 9am, noon, 5pm and so many other times nothing. Up until the last couple of months, the mobile banking was pretty consistent. But since about August, it is days at a time unavailable. I am closing my accounts if this persist.
