water overflowing corner gutter

[newbuyer17]

When it rains the water overflows the corner gutter on our house.

I've not been up, and suspect there is some blockages, but dont think its a blockage as such that is causing the issue. Its like the corner piece hangs down slightly, and the very corner is the lowest point.

If I push up on it (as per the red arrow) with a broom handle I can stop the water flowing over. Then as soon as I let go it drops slightly and starts again. It may be that I just give it a chance to fill a bit more, and ultimately it would start leaking again, or it may be that this is just the lowest point.

From what I can see, it is a right angled piece, approx 9" long each side, and is supported at the end of each side. There is no support that I can see at the actual corner/right angle/middle bit.

Is this likely to be the problem? Can/should it be supported at the very corner?
Or can I easily lift this edge up somehow? There is a metal hip iron immedately above it, and wondered if the guttering could be tied to that to hold it up?

I should confess, I've not been up there on a ladder, and also I'm really not great on ladders anyway so wouldn't want to be doing any drilling or whatever up there? Is there a quick fix, or do I need to get someone in?

Thanks

Maybe there's a crack along that corner, time to get that long ladder out.

The guttering might be improperly fixed with the corner at a very low point.
As above,someone has to go up and observe during a rainfall or using a hose for a water test.
I suspect that water is dripping down the back of the gutter runs.
Perhaps the felt has been stopped short, and isn't lapping over the gutter.

Your photos dont "work". A photo of the whole side of the eaves line would help.
