Real racing 3 additional data not downloading

I’m facing an issue with Real Racing 3 where the additional data fails to download over my 5G connection, . Despite having a stable 5G connection, the download won’t start or complete. I’ve checked my settings to allow large data downloads and tried clearing the cache, but the problem persists. My device is iQOO Z9x 8 GB ram and 128 GB rom, and I’m using 5G network on my phone. Could you assist me in resolving this issue?
