Harry has been warned, strenuously, by Professor McGonnagal that he should not directly interact with himself
I forget if we’re discussing MoR or canon, but either way I object. In canon, my objection is pedantic: it’s Hermione who was warned, and she only later passed on that warning to Harry. In MoR, Harry has interacted with himself, a few times, and while they didn’t all go well, there were no disasters.
“Correct, I think,” said Professor McGonagall. “Although wizards are advised to avoid being seen by their past selves. If you’re attending two classes at the same time and you need to cross paths with yourself, for example, the first version of you should step aside and close his eyes at a known time—you have a watch already, good—so that the future you can pass. It’s all there in the pamphlet.”
“Ahahahaa. And what happens when someone ignores that advice?”
Professor McGonagall pursed her lips. “I understand that it can be quite disconcerting.”
You’re right, I misremembered. Still, I think there is a lot to suggest that interacting directly with one’s time-clones (as opposed to waiting with one’s eyes closed while a clone drops off a message, for example), particularly in battle, is a bad idea. You would never observe a future-you doing something ineffective in combat—failing to dodge or block, or casting an ineffective spell, for example—since, after observing that mistake, you would be prepared for it in the future. So the only consistent possibilities involve losing or running away before you can go back in time, or winning right away.
But, since you know these are the only consistent possibilities, if you showed up to a battle intending to use a Time Turner and didn’t see your time clones appear at the very beginning, you would deduce that you would not win, and therefore (if you could) you would run away. So, I expect that from Time’s perspective, the most stable solution for people who intend to use Time Turners in battle is for them to not do battle at all.
He has never interacted directly with himself in a way that involves seeing a copy of himself, or coordinating actions in real-time, as would be the case in a battle. Harry has so far always heeded Professor McGonnagal’s advice, and looked the other way when his time clones are around. Though, as pedanterrific points out, I have overstated the severity of McGonnagal’s warning.

Not that strenuously:
