Importing Mixamo Animations into Unreal does not work - urgently need help

Simply trying to import animations from Mixamo to Unreal. Importing a single animation gives this error.
“mesh contains root bone as root but animation doesn’t contain the root track. import failed”
A simple google search shows other people also are experiencing the same issue and link to this tutorial, however, the link goes nowhere.

Many sources claim this is the solution, as late as 2019. I don’t think the solution has been archived anywhere.
So my question is, how is it possible to fix this issue?
Any help is appreciated, I will keep attempting to find solutions in the meantime and update the thread if I come upon anything useful;

I think I found a workaround! I uploaded the mesh of the UE4 Mannequin onto mixamo. Downloaded with the skin included. Imported it into Unreal and it worked! Was also able to successfully retarget a characeter model to the mannequin with the animations.

Update: Any animations I make in mixamo have floaty feet. I’m not sure how else to describe it. It’s more noticeable in certain animations. Here is an example.
What the animation is supposed to look like Screen capture - 6ba15e7e6c15b2e211e883929b0af361 - Gyazo
What the animation looks like in Unreal Screen capture - 8bd98d6f68b6f87caaa149458cc300bf - Gyazo

Here is another example.
What it’s supposed to look like Screen capture - ae980e67a7d8297248ee44f2bb87166a - Gyazo
What it looks like in Unreal Screen capture - 142cecd548a30b4610719b258c229f5f - Gyazo

It’s just especially frustrating because it wasn’t too long ago that mixamo disabled their ‘export for unreal’ option.

I may have found a solution, bless whoever wrote this Retargeting Mixamo In-Place Animation To Epic Skeleton - Community Content, Tools and Tutorials - Unreal Engine Forums
