Low volume when using Auto-on feature Revolve Soundlink
I have an issue with my speaker (Revolve Soundlink) regarding the Auto-on feature. When I start my speaker with Auto-on on my iPhone, the maximum volume is not very high, but when I turn my speaker on and then connect my phone, the speaker can get WAY louder. I tried with several iPhones and the same issue, but with a MacBook, it's working fine.
I tried to reset with 10sec power button, with 10sec multifunction button, and with both button for 10 sec but the issue is still there, I feel like it's a firmware issue.
Is someone having the same issue? Is there a fix?
