While it is possible to have both the HarmBlock+ service and Google Family Link in use on HMD Fuse, in most cases, Google Family Link will not offer any additional functionality on top of HarmBlock+.
If you decide that you want to use both HarmBlock+ and Google Family Link, we recommend setting up the HarmbBlock+ service first and skipping the Google account setup stage on the HMD Fuse phone. When the HMD Fuse is ready to use and linked to the parental device, you can set up Google Family Link.
In addition, we highly recommend turning off the app management feature of Google Family Link as this can cause a conflict with the same feature in the HarmBlock+ service.
Please note that Google Family Link will block the remote factory reset feature of the HarmBlock+ parent app. To factory reset HMD Fuse with Google Family Link installed, we recommend unpairing the phone from the parental device, then using Google Family Link to factory reset HMD Fuse.
