Anyone else having an issue with heavy attacks going through randomly when doing a 5 combo?

I use an iphone 8+ for reference and sometimes my character will use a heavy attack instead of finishing a 5 hit combo. usually in the middle of the end. ive made sure not to mash buttons or doing anything that would cause it to happen, but it still does sometimes and it messes me up. Even caused me to die in AW which is frustrating. if anyone else is having this issue please comment!

Same device as you. It’s very rare but sometimes it’ll do it a heavy on the 2nd or 3rd hit when I’m not expecting it. It’s rare enough that I don’t see it as that big of an issue but when it does happen you can end up taking quite a bit of damage being knocked out. Not sure what causes it so hard to get a video because it’s so rare. Only one I can remember it happening with is hulk, not sure if that would be of any relevance.
