Most people see "flushable" and don't actually read the instructions (1 per flush, among other things) - they just throw 2,3,4,5 of them down the toilet at the same time. That's how you get these problems.
Never!!! I deal with this issue all the time. Just because it says flushable doesn’t mean it should be flushed. Even tissue paper shouldn’t be flushed. You want to show anyone what can and can’t be flushed just put toilet paper in a bowl of water and then any other product and see the difference.
Every plumber on social media I've seen talk about wipes, even if it says flushable, say to stay away from them. I guess they're not regulated on what they can put on the packaging and realized they can advertise "flushable."
