Infuse Cloud service not working

i purchase infuse 5 pro after coming 6 i subcribe 6 for 3 year, now i want infuse 5 pro but cloud service not supporting

The Infuse Pro 5 app can still be used, but you may run into issues with newer versions of Apple’s software or connecting to cloud services, as both have changed quite a bit in the last 7 years.

For the best experience and compatibility with current Apple software and services, I’d recommend using Infuse 8.
