Rundown for the newest readers.
Duckling was done (24/7) last March/April. As in 20-mos. I went to a funeral, and didn't see her for a few weeks. I was being punished for not taking her while I was gone.
Potty training was 100% forgotten. She pooped her pants twice. Then one long 24 hours, she was constipated bad! I actually had to keep her in my bed so that I could rub her back, and try to help her deal with the pain when she had to push. During the day, I took off her diaper, and put her on the potty. Of course, she didn't want to sit still during the pain. However, it honestly didn't take much to keep her there. The correct BM position helped her immediately. The next time she had to go, she actually told me she wanted the potty. No more poop in her pants while here.
I still encouraged potty use from May to... whenever I couldn't afford to keep diapering her. Then I used a potty app, she liked it, and was done again. Nights were only re-mastered a couple months ago.
Her other family members didn't try to potty train. She told me her father wouldn't let her into the bathroom to go. I witnessed her parents ignoring her too.
Recently she looked at me afraid, and asked if I was going to hit her for the accident.

Yes, it was confirmed today by her mother. She's bad and hit for accidents.
My point, newer people, is that while setbacks are normal, they are more so for her.
Btw, she was dry for 24 hours. I said she was going to see her parents... never fails. That has been a proven way to make her pee all along.
