Dreame Bot Mihome not linking again

[yms7]

Hi all.. Untill yesterday I was able to use Google Assistant to start my vacuum cleaner (Dreame F9) Yesterday I unlinked in Google Home my "Dreame Bot MiHome" account as I wanted to rename my vacuum . So I wanted to relink it in Google Home. Now I am receiving an error message, saying "could not reach dreame bot MiHome. Please try again". What's going on? I have reinstalled apps. Factory reset my vacuum, but nothing helps.... Could you please help me... I miss being able to use Google Assistant to start my vacuum.

No use from dreame customer service, they are so unaware of how their product works 😢

Struggling with the same problem!

I can remove the linked "Dreame Bot MiHome"-account from "Google Account Third-party apps & services" and the Xiaomi Home app. Both are getting added again, when trying to link "Dreame Bot MiHome"-account although it says it can't link to "Dreame Bot MiHome"-service, try again later.
I also removed Google Home app, downgraded Google app, cleared storage and cache of those apps. Nothing helped. According to https://www.googlenestcommunity.com/t5/Apps-Account/Google-Home-not-linking-Dreame-bot-MiHome/m-p/32... problems like this already existed.

Any advice would be helpful. Thanks i.a.
