well latex is water based and any way for the water to get in and behind it is wy it bubbles and flakes. get an exterieor paint from your local hardware sore. I prefer Behr primer and paints for outdoors. Have them mix it to your color liking and paint it.
Find the best stripper to use by experimenting. I think you are on the right track already by what you said. So, try it more. But otherwise, ask the paint center about strippers and techniques that work the best for your area. Hope this helps

It sounds like you have a moisture problem. Do you know for sure that a vapor barrier was properly installed with the insulation? I’m surprised that a latex primer was used since oil is better at preventing tannin stains from bleeding through… unless the topcoat is a color that conceals these stains..Anyway.. you might need to install some 1″ diameter vents at the top of the walls to vent moisture out of the wall and/or use dehumidifiers to control moisture inside the house during days of mild temperatures & very high humidity. You might ask a paint dealer about using elastomeric paint as well.
