| | Re: Vanishing Contacts?
Following BlackBerry's advice, I restored my Q10 to factory settings and then re-entered my iCloud account for both mail and contacts. I have elected to leave LinkedIn and Facebook contacts off for now. After 24 hours I can report no issues with vanishing contacts or phantom linking of unrelated contacts. In another day or two I will enable LinkedIn contacts and see how that goes.
One thing I studiously avoided was enabling Verizon's BAPlus (Back Up Plus) free in-house cloud based backup. The moment I toughed that piece of crap all hell broke loose with my contacts.
