Blackberry Q10 stops syncing with icloud contacts
We have a BB Q10 on Verizon and although I am able to add my icloud acct to the device to access email, contacts and calendar, contacts stops synching after a few days consistently. I have removed the icloud account and added again but it stops synching after a few days. More specifically, I have 654 contacts. After a few days, it will only show me 30 or 40 contacts. No rhyme, no reason. Please help.
