i have altura flash that worked very well in TTL mode on my canon t4i rebel 650D.

The same flash on the t7i rebel 800D works on the one hand but the camera keeps saying it does not recognize the flash.

Note that the flash recognizes when the zoom is changed on the lens as well aschanges in aperture. It correctly displays both on its display.

Also when i change flash settings (such as flash exposure compensation) on the flash itself, the camera shows them on its display.

But... the camera still says unrecognizable flash. Remember the t4i 650D had no problem

would appreciate any help with this

thanks in advance

Canon has been changing its flash communication protocols.  Maybe that has something to do with it.
