Configuring Tuya integration

Hi there,

/!\ I am completely new to HA so if this is not the right place to post or what I am saying is not clear, please be forgiving.
And please do not assume I know anything if you are responding to my distress signals. I did try to search for similar topic too. Thank you for your understanding and help /!\

I have installed and configured HA using HAOS on RPI4. So far no problem
It has detected a buch of devices that more or less went fine (some google stuff, wifi router, …)
and some Tuya devices. Trying to put the details required to login (username, pwd, loc code, app), but it fails with “Invalid authentication”.
I am pretty certain it is the right password, login, information I provide given that I logged out and back in on the android app to ensure my credentials were correct.
I checked the logs and there don’t seem to be any error displayed there

What could be the problem?
I also searched around a bit and there was discussion of a Tuya v2 but this seems to be archived, as well as an official Tuya integration.
Should I check this out?

Thanks!
