Hi @Lara_M,

Can you indicate which specific version you are using (e.g. 3.3.0-8)? This is helpful to include on posts here in the forum as it assists others in being able to troubleshoot.

It’s the 3.3.0-11, the LTS version.


Hi @Lara_M,

Thank you, for clarifying. FYI: 3.3.0 is considered our LTS version:
