I bought a godox tt600 2 weeks ago, i used it first time on cameracfor a wedding ceremony it was working perfectly in the morning on 1/16 mostly, but the reception was in a hall and was dark so I was using 1/1 boncing from the white ceiling, at the end of the ceremony money it started malfunctioning, the red button would ready to flash, but it wouldn't glash, I tried several times keeping it at rest for some minutes it would flash once then it wouldn't flash again, I left it to use it again yesterday on 1/2 it worked on most shots but sonsometi it wasn't, today it just worked on two shots now it's not flashing but the batteries have power, even the test flash can't work, I have been using on manual mode, my camera is Canon 1200D,

Repeated full power flash with a speedlight can damage the electronics of your flash.  Most speedlights require significant down time between a set of full power flashes.

For example, the Olympus FL-50R required 10 minutes rest between 10 full power flashes.

The problem with shooting TTL is that you have no idea how much power the flash is putting out.  You need to experiment with the flash to determine what camera settings will typically result in lower power output, such as 1/4 power.

Or, you invest in a flash that does not suffer from such limitations.  I use bare bulb flashes such as Quantum or bigger Godox.

Note also that Godox, while nice gear, may not be the most reliable equipment for professional use, such as for a wedding.  Although I do use it when I want to keep things light, I have backup and keep an eye on the power levels.
