Hi, can you DM us on Patreon? We will sort this out. Sorry for the delayed response.
Since Quest2 v51 or later cannot install "MU5", so it's already worthless.
I don't care if the post from a year ago is correct or not, but rather than that, Can you tell me the download link for "v53fix"?
I think that you should send a DL link by message to all applicable users of $ 7.5 or more of patoreon.
I was able to install and activate by re-downloading MU5.
"Quest version now supports v53. Download page is here.(file replaced) https://www.patreon.com/posts/60228876"
Why can't you even say this? Why should I, the user, explain?
