Architect homes gone

Been playing the sims free play game for over 7 years now and this is my first time having an issue with the game .. Ever since the “New architect homes “ update came out it’ll only show me the houses and give me the option to buy the houses for 1 day and then they disappear until the next set of houses come out !  I play on my iPhone 14 and I was wondering if I was the only person running into this problem and how could I fix it ?
