Trouble loading TIDAL content in Roon

I used Roon Rock previously on an Intel NUC 7i5 machine and worked well before 1.8 update. After that Tidal functions stopped working, the only albums could be played were the ones which were saved in my library. That was the inital problem.

However since that I tried to install an other core to a win10 notebook which worked flawlessly but prior to use I was asked to deauthorize my Rock core. After I cannot step back to that optimized core. It does not ask me to deauthorize the win10 core just spins the progress circle then times out.

I tried to install win10 also onto that Intel NUC machine. It was also working flawlessly and finally asked me to deauthorize previously used core on the notebook. I thought this solved the machine authorization problems.

However when I reinstalled Roon Rock to that NUC machine I could not enter it again. No any way to enter to my Core if it’s running on that machine under Roon Rock.

Sideinfo: Now I reinstalled win10 again just to have the opportunity to play music and I noticed one thing. In spite of having my other previos cores uninstalled from everywhere I still see them and their Audio Devices as Roon Endpoints under Audio tab of the settings. So… I think the backend somehow saves informations all of my previously installed cores.
I think if this settings would be cleared and completely purged from my account then I would be able to register a new core even under Roon Rock.

So please… purge all my roon core related informations from my account.
Please
Please
Please!

Thanks!
