I’m also having issues updating my H9max. I haven’t used it in about a month and a half. Went to update it with my Iphone 6s+. No joy. About 10 times. Downloaded H9 control for my Macbook Pro. Tried via bluetooth and usb. No joy. About 10 times. Tried every permutation of bluetooth on/off. Cable in/out. Either I get the “can not connect”, “too many tries” message or it gets to about 42% and it stops due to “device hasn’t responded in 5 tries” or something like that. I updated any outstanding updates on my Macbook. I have 9.3.3 on my 6s+. Is it time to send it in to Eventide? I purchased this new in March or April this year.
