Eufy Scale won't connect new iphone 11

So I upgraded from my iphone Xs Max to an iphone 11 pro max, and used the eufy scale for the first time today. It didn’t connect, so I pushed rescan as it asked but didn’t connect. I opened bluetooth screen thinking I needed to connect there, but while I can select it, it connects for a second then goes away. Any suggestions? Do I need to uninstall, reinstall the app? Seems like that wouldn’t fix it but open to anything.

A lot of people are having issues with using older items in bluetooth with the new iPhones, it’s a software incompatibility issue and either a firmware update can fix it or a replacement may be needed. Send a message and they will further assist you
