App is still crashing and I'm very surprised that you cannot create new patches or name them without using the app. Even my trusty old Line 6 M5 can do that and it has half the knobs & switches of the Firehawk. I am very concerned that the next iOS update may break the app completely, rendering the unit virtually useless. Looks like I will be reluctantly returning it to the shop.
Took delivery of a Firehawk FX yesterday and overall I am extremely impressed. However I am experiencing a lot of crashes with the app which is running on an iPhone 8 with the latest iOS (11.2.2) Every time it crashes (6 times in 2 days use) I have to wait for the pedal to finish syncing. I notice that the app hasn't been updated in 8 months, have Line 6 been neglecting it in the wake of Helix?
