Pro features were working fine between Mac-iPad-iphone 4S. Upgraded to iPhone 6 and pro features won't open on new iPhone. All devices signed into icloud with a me.com address. Using iCloud synch. Tried deleting 1password several times and reinstalled directly to device. Not sure but I think pro features were purchased with 1password 4 installed and and 1password 5 upgrade went smoothly. Running Yosimite and latest IOS updates.
