Nabu watch forged edition is not syncing with the nabu android app

Hey guys, So today i got my Razer Nabu watch forged edition. Unboxed it, charged it and installed the Nabu app on my phone (One Plus 6T | Android version: 9). After installing the Nabu app i gave all the permissions and switched on the location and bluetooth post which tried adding the Nabu watch from the app home screen. The watch gets found/detected on the initial screen, long pressed which showed me the 4 digit number and entered the same in the app. Then it connects and starts the "syncing" screen. It goes on showing the syncing message for almost 30s - 60s and throws message "syncing failed, error". I tried syncing it multiple times without no luck of getting any further. Also tried, - uninstalling and reinstalling the app - re-logging in to the app - gave the permissions again - switched off/on the location and bluetooth Not getting any further, can somebody help me please to get this sorted. Thanks in advance.
