Just for information,

I have tested with the long term Stable (2.9.10) and the latest feature oriented version (3.4.0) and they both works as expected.

I used 3.3.2 and then tried with the new 3.4.0 but still not working. Ok thank you for the feedback, it must come from something on my side, I'll look more into that.

Sincerely,
