My speedlight Canon 580 EX ii goes automatically to ETTL when I turn on my Flashpoint R2 tigger.
When I turn off my R2 trigger all the functions on my 580 work. I can switch from ETTL to Manual. If I adjust the power with my XPro C to set my 580 the flash fire in full power. No power adjustment can be made on the flash nor does the flash accept the power settings from the main trigger.
How Can I fix this issue?
