I never use it on my R5, not even for settings. I can't quite put my finger on it (pun intended) but for me Canon's touchscreen implementation always felt off.
I'm 100% sure I'm in the minority with that opinion as everyone always praises Canons touchscreen implementation. But from the first Rebels that had it to now in the R5, the screen seems to react unnaturally early, just before my finger actually presses down. Basically I find it too sensitive even on the "normal" setting. Never had that issue on any smartphone. Might be a personal thing, but that's why I never use it.
