Even when they do tell you it's ok, it's probably not ok. Toilet paper is designed to disintegrate rapidly in water, hence why it's easily flushable because by the time it's actually going down the pipes it's all ripped up already. Wet wipes, even the "flushable" ones stay intact. You can try this at home, take two cups of water, in one put in a few sheets of toilet paper, in the other put it a wet wipe. Stir them both for a minute to simulate flushing them down the toilet. The toilet paper rips up and what clumps are leftover are pretty small. Wet wipes stay completely intact, which is why they cause problems down the line when they're flushed.
