Nothing that really effects me since I don't participate in Rivals. I really wish they would fix the guitar solos though. Every update I hope it's addressed but no one seems to talk about it at all.
Which sort of guitar do you use? Have you tried posting about the issue on the RB subreddit? People usually answer things quickly and they have HMX employees around often enough that one should see it.
I'm using GHWT guitar AKA the best guitars out there.
It's not the guitars, it's always fine expect for during solos. Idk if it's a new mechanic or what, but if you press a note early, it breaks your streak. It's pretty infuriating to have your streak broken but still hitting everything. I just feel like I'm the only one that this is bothering/noticed.
