I have recently purchased a Galaxy Watch 6 LTE to use with my GrapheneOS phone that does not have any of the Google Services apps to be downloaded from the "Apps" container. Let´s call them GPS.

I proceeded to download the following apps frmo Aurora Store
Samsung Wearables, manually gave it all the available permissions.
WearOS (Requested by Samsung Wearables). This app installed in Chinese for some weird reason

It did not work I learnt I needed GPS for it to work, so I tried on a second profile where I had GPS apps, it did not work.
I learnt it had to be on owner profile. Went on Owner profile, Installed GPS, initiated Wearable App, connected the watch, accepted all Samsung´s terms and conditions, including optional ones, accepted google conditions, excluding diagnostics and All worked fine, watch was perfectly connected.

I learnt that my Watch had stored an Esim from the previous owner, in an attempt to respect its privacy, I went ahead and reset the watch to remove that esim/phone plan. Here is where everything went down
After the reset, I went on my phone, opened Wearable up, attempted to connect the watch to it. Connected the watch by confirming the pin number on both my devices (phone and watch). Accepted only the required Samsung´s Terms and Conditions, accepted Google terms and conditions. ERROR message received. Here is were my nightmare starts.

I thought maybe there is some conflicting data on the apps so I tried all the following:

Clearing cache and data of Samsung Wearable App and begin set up again
Clearing cache and data, uninstall and reinstall of Samsung Wearable App ....
Clearing cache and data, uninstall and reinstall of Google Apps ....
Restart my phone after re-installing wearable and GPS...
Downloaded Wearable app from Aurora Store
Downloaded Wearable app from Google Play Store
Manually turning on all permissions for Wearable , Same with GPS
Manually turning off all Wearable Permissions, then accepting them upon installation, same with GPS
Reset the phone after going to Play Store, Google Play Services, and every single Google app manually, settings>permissions>nearby devices & location
Accept all Samsung Optional Data & Google optional Data upon set up..
Attempt set up with both Location On and Off..
Factory reset the watch from boot menu...
Update the watch from the watch itself by connecting it to the wifi and try to pair it again
Did the UNTHINKABLE Registered a google account on my Pixel phone in case that meant anything
Registered a Samsung account but haven´t used it yet.

Tried the phone on a spare normal Android Samsung phone:
Installed Wearable from AuroraStore
Paired the Watch
Everything worked perfectly
Tried again on my Pixel with GOS, not working.

I do not understand two things: 1. Why it worked perfectly in the beginning and then after the watch reset to try remove the previous data plan everything broke. Did I update the phone in between these two things? Can´t remember but don´t think so there are no updates to be done.

ANY HELP APPRECIATED I WANT TO USE MY BLOODY WATCH ALREADY
