I also had one migrated and the left on GD, safe to say the transfer from GD to Cloudflare for all of the non migrated domains was very quick. The one on Squarespace is taking days to move. It took several hours to get the transfer authorisation code and now I've been waiting days for the actual transfer to happen. I was very happy with Google Domains, however I'm not surprised in the least that they killed off the product as they seem to do for everything.
I ran into this problem recently too, i found https://www.helpwire.app as an alternative, it was very useful as it clearly showed me what step the client was on to start the connection. However it doesn't allow unattended access, I will likely use a combination of this and Rustdesk
Hey, just so you know, it seems like it's possible to get stuck during the onboarding journey (No option but to refresh the page)
I tried the app using the 'no account' option. At the end of the exercise, it asked me to sign up to see my results. Clicking on 'sign up', I filled in my details only to find out that the email apparently already is in use (clearly, I've forgotten signing up). It recommends I should try logging in instead. However, there is no way for the user to log in at this point without losing the test task and totally restarting the journey.
The Youtube Description states the inspiration was this:
"After seeing the documentary "Alone in the wilderness" by Dick Proenneke, I became completely obsessed with the idea...."
"I know my journey and I hope to inspire others the same way Dick Proenneke inspired me."
