I've 14-Pro and I recently did update to "iOS 18 beta" using beta channel.
However, the first I noticed was a deleted call-history...
After several tries (using tips from forums), nothing showed up.
Finally, I did reset all and reverted back to "17.5.1" and used the last iCloud backup (right before iOS 18 upgrade).
Call history is back, however it is limited to "only 1-month" back in time! Why?
I've 2 TB iCloud storage, why my call history is gone why?
I keep backup of everything, and call-history contains very important details as well.
Please help in getting back my data asap.
