Polar Loop 2 sync doesn't start in FlowSync. Now what?
Try these steps, one at a time. If your product doesn’t charge properly, or if it doesn’t connect to FlowSync, it could be because the charging area on the back of the product is not clean enough. You can wash the device with a mild soap and water solution under running water. Wipe it dry with a soft towel, before you charge it. We recommend you wash the device on a regular basis. Do NOT use alcohol, cleaning chemicals, or any abrasive material such as steel wool. If your Polar Loop 2 is shown on the list and the synchronization does not start, send the FlowSync log file with a problem description to customercare@polar.com. If your Polar Loop 2 is not shown on the list, either Polar Loop 2 or the USB-cable is faulty. Please take them to Polar service.Check that Polar Loop 2 charging area is clean.
