Adobe Lightroom License not being detected

Below is an overview of my experience so far:

1. I bought a license for Adobe Lightroom from the Microsoft Store which included a 1-week trial.
2. I tried the bullets at the bottom of this list*
3. Managed to get in-touch with Support on Saturday evening. They asked me to follow a number of guides, including deleting the Adobe certificates and uninstalling/reinstalling the application. None of it worked, but they said someone would call me Monday at 1430 for a call.
4. Monday at 1445 - nobody called, so I messaged support. Support again asked me to follow a guide on removing my certificates and, this time, added the cached credentials in the credential manager. Didn't work.
5. Another support representative asked me to visit lightroom.adobe.com to see if it worked - which it did, except I couldn't upload images for some reason.
6. Another support representative requested that I give them complete control over my computer and turn off all antivirus/security software and that this, apparently, was the only way they could support me. I'm sorry, but this is bonkers. I am more than happy to conduct actions on their behalf, but I do not want them taking over my PC. If this is the only way of providing support, then Adobe needs to revaluate itself and its policies.
7. Finally, another support representative is now asking for my contact details so they can arrange ANOTHER call back service.

• I've uninstalled it and reinstalled it from both the Windows Store and via my Adobe Account and the Creative Cloud Desktop app.
• I've logged out of my account and back in via the "Help" menu on the task bar.
• I've tried to force the application to update to see if that forced a 'sync'.
• I've tried running the application directly and over a VPN connection.
• I've tried connecting to the cloud storage option to see if that forced a 'sync'.
• Tried a password reset on my Adobe account.

I've just had another support representative demand that the only way he could provide support is for me to provide complete control over my computer and turn off my Antivirus software.

What kind of show are you guys running? What sort of request is that? This is bonkers!

Been trying to fix this since Saturday. Reached a point where the weekend team could go no further and was told that someone would call me at 1430 GMT. Nobody rang, so I messaged in.

Guy I then spoke to didn't read my ticket history and made me explain it all again. Asked me to carry out some actions (one of which I'd already done) and restart my PC. Did that, still didn't fix the issue, when I came back on, I was put on to someone different again. Who then made me explain my issue again instead of reading the ticket.

This is legitimately some of the worst support I've ever received. My trial will be over by the time I even get to use the damn thing.
