Yes, the version matters because older versions which are no longer supported don’t get updates.(Which also means if there’s a bug and it got fixed, it’d not be automatically backported to the unsupported older versions.)
Thank you! I hope you find a solution in the instance that you are using. @janagha it might still help if you share the logs from the console and network tab (in dev tools) so it might give a hint about how solve the issue.
