No clarity from Multiply on relinking of fitness device

I have asked 3 times for clarification as to why and how to relink my fitness device to the multiply app. I’ve received multiple comms telling me I need to do this by end of Dec in order to keep earning rewards in 2025 (active dayz). I’ve asked for clarification and twice received info that I need not relink my device. But after receiving another sms reminding me to relink my device I’ve requested clarity again, which has been left unanswered since last Friday (20 Dec). This is beyond frustrating!!
