Help on data download in Sims Mobile

Hello everyone ans EA! I need help with my The Sims Mobile game. the game always makes you redownload data after an update, i know that. but this time, my download process keeps resetting even though i didn't leave the app for a second. i have to download 1,044 mb of data. But when the progress reaches 789 or near 800, my progress just restarts at 300 for absolutely no reason. It's frustrating, I don't know what to do. I reinstalled the app but the issue still isn't fixed. Can someone help?
