Who I have the same questioned this topic

I have verizon Messages on my android phone. However it can't sync contacts with the Verizon Cloud. I get the following error message when I open "Apps using Cloud": "You haven't given any apps permission to use your cloud." On my Android Marshmallow s7 edge, how do I give verizon messages permission to use the verizon cloud? Seems really poor that the two apps don't work together. Thanks.
