Not eligible for sapphire, reserve sign-up bonus

I opened a sapphire preferred account in May 2025, recently tried to apply for the 150k Reserve offer, however, was told that I was not eligible for the sign up bonus. Does anyone know when I would become “eligible” for new account bonuses? I opted to not move forward with the application.

Also, I opened a Marriott Boundless account in November 2025. Not sure if this would impact the eligibility for the Reserve?
