I mentioned a similar problem here:
I sent you a private message about this issue, with the manual/scoring on the forum in July of last year, and never got a response. Not sure if you can click on this directly, but: https://www.vexforum.com/t/vrc-hub-issues/48852
It is still happening, it hasn’t ever stopped. My phone is currently at 8gb free, but it has been lower before, so that could have potentially caused it a while ago, but not now. If you need me to test anything. I’d be glad to help. I asked around, and it also happens on two of my friends phones, and they just assumed the manual downloaded every time the app was opened, and it was working as intended.
