Godox AD300 Pro Has One Problem

**please see updated below**
The Godox AD300 Pro has one problem, it's native stand attachment can not handle the leverage of it's largest native modifiers, such as the Godox AD-S85. In this video I go over what I've attempted to get around this, and ultimately the solution that I'm currently using, a Mag shoe with 1/4"-20 to cold shoe plate.
I'm hoping the viewers of this channel have a suggestion that doesn't cost $60.

**Update**
1) I talked to Godox more about this and they said it may be a pre-production / limited issue as they did make adjustments to it, so I'm currently awaiting their current one. But they said most users should not experience this.
2)This is not an issue with it's native reflector, long throw reflector, snoot, small umbrellas, etc. I experienced it only with the AD-S85, and a bit with the AD-S65 although I can tighten it down enough with the AD-S65 to minimize it.
3) Regarding S2 bracket. I love it! But, my whole purpose of this is for minimizing size of kit for travel purposes, taking advantage of the smaller modifiers. In a 2/3 light kit, S2 brackets vs tiny mounts is a big difference in packing.
4) per commentors the Manfrotto lite-tite umbrella adapter does seem like a good option if you are also experiencing this issue. $30 Cheaper than Magshoe.
5) I tried locking washers, they didn't work.
