Samsung Billing app not allowing to switch facer watches

Hi Support,

Recently noticed that if I tried to switch watches faces on my watch using facer I am prompted to install Samsung Billing application (update it), in fact the download starts on the phone but the result is always the same : application error and if I retry same result over an over, so I am always stuck with one face watch and can’t use other faces, I have reset samsung apps clear cache and nothing, please advice (using android 6.0.1) and Galaxy Prime J7

I have been getting the same msg but I have not installed the billing app. Mine still works (changes faces) but it is a bit annoying.
