Ewelink stopped working

Hi. In Italy i have the same problem. is there a solution ? no more possible for me to login into ewelink on THR. Same error
Sign:oauthClient
enable invalid

Is any work on restoring functionality underway or is it an abandoned topic?

I’ve read a bit and since 2020, when the API was published, there was no change to it.
The author hides the real reason for disabling support.
I am abandoning this app completely.

What idiot marked the topic as solved?
