Potty training and new rooms

Hi everybody, quick question. I have a new puppy, about 12 weeks old, and I had a couple questions about potty training. When she’s in the crate, she does fantastic of letting us know when she needs to use the bathroom. She’ll be sleeping and then all of a sudden start waking up and whining, and that’s our queue for her to use the bathroom. Pretty reliable, getting to 3 1/2 hours now

The issue is when she’s in the house under supervision during the day. So her room is the sunroom that we have in our house, which is where her crate is. There’s a door right next to the crate which has a jingle on it, which she intermittently will ring when she needs to use the bathroom when she’s out of her crate. She is not the best at understanding how to jingle the bell. I’ve been trying to teach her to jingle the bell before we go outside by putting my hand right behind the bell, but she doesn’t get the hint and just tries getting to my hand rather than hitting the actual jingle. Trying to manually move her head to hit the jingle is a little challenging.

I found that sometimes when we’re in the living room, which is adjacent to the sunroom, she’ll randomly go into the sunroom and have an accident. I haven’t really picked up any cues yet to hint at her needing to use the bathroom. She doesn’t whine like she does in the crate.

I’m looking for some advice on how to navigate this. I understand that she’s a puppy and that they’re going to be mistakes, which is totally fair. When she has these accidents, I Don’t have any reaction to it and I just cleaned it up and use enzyme spray to try breaking it down so that she does not continuously make the association of pooping or peeing and the room. We have three bedrooms upstairs and I’m trying to do supervise playtime in one bedroom as a way to let her explore a little bit more but she just recently had an accident in the five seconds that I did not supervise in one room as I was getting water. Any advice would be super helpful. Thank you!
