Godox issues with the R5 are only if TTL and HSS are used at the same time, right?

I don't use TTL so just want to make sure I am understanding the issues I have seen reported in some places. It seems that it is only when using TTL and HSS together but not, like in my case, when I use HSS only.
Thank you!

I emailed Adorama about this issue. Godox is aware of the issue and have not released a firmware update yet. Apparently it has too do with the pre-flash in TTL with HSS. The pre-flash doesn't sync correctly with the R5 so it just pops at full power since it doesn't see any light from the preflash. So you can't really say just FEC -3 or whatever will work. It will all depend on how much full power will affect your shot.

And from my experience is this is only an issue with off camera flash, not when mounted to the camera.
