flash - Yongnuo YN-568EX (for Nikon)
I successfully learned the profile and things were working as advertised but I then had a problem with the flash and sent it back under warranty.
When my replacement flash arrived the learned profile no longer worked. So I went through the learning process again, and it was successful. Even though the learning worked I am unable to change power output. For reference with the flash in manual without the V6 it looks like its firing at about 1/16 power.
Any idea why it wouldn't work this time around with the same model flash? Why learning would be successful but not be able to change power?
Any help would be appreciated, thank you in advance.
