Can't ping ammo, just says "there is an arsenal".

This doesn't mean that you can't actually ping ammunition. In fact, you can, but the specifications are set to ping the armory afterwards, and because of the priority, only the latter half of the voice is played. You can see this by looking at the log. In other words, it's not a bug.
However, I'm not satisfied with this specification, so it should be fixed. Because even if you ping the armory, your allies aren't smart enough to go in that direction.

What the heck do you mean? Before when you clicked on ammo with middle mouse button (as I have) it said "I need light ammo". Now it just says "there is a light arsenal over there". So I cannot request ammo from my teammates anymore. It's superannoying

Maybe it makes a difference because you're not pinging ammo, you're pinging the weapon to request ammo, but then your logs will say "Ammo request -> ping armory", even though it doesn't make sense to ping the armory for an ammo request in the first place.

If you ask me what that means I'll just say it literally lol

I tested it, and the behavior after the update is as follows. PS5.

• When I ping a weapon directly, it requests ammo and then pings the nearby arsenal. ← This is unnecessary.
• When I ping ammo directly, it requests ammo. It does not request the arsenal.

same issue here.
i am assuming the devs in this game they are not actual players of Apex. their brains fart an idea and just implement it without knowing the real impact on the game. ffs...
