Harmony/SmartThings integration - Signing into Logitech through ST does nothing

Having difficulties integrating Harmony and ST.

When I go to Marketplace and add the Harmony Home Hub, I get the first page where it asks me to enter my credentials.
I tap on it and get redirected to the Logitech sign-in page.

I select Sign in with Google, since that’s my account there.
It then directs me to enter my Google account name, then my password.

Once I submit that, I’m then told to “Please close this window”.
I hit Done at the top and it takes me back to the first page.
If I hit Next on the top right (the only option other than to sign in again), I get taken to a blank page with a Done button.

That’s it.

Just chatted with ST Support. Apparently there is an issue occurring with this integration.

Yeah, others report major issues on Harmony side. Harmony is notorious for breaking ST integration with their updates. I haven’t used it in almost a year now because of that…
