Maintenance windows report does not match debug output

[Manimi-Chart]

I updated the maintenance window on my sensor but the report did not reflect the change. I enabled debug mode and ran it manually in PowerShell. That does have the updated window:

PS C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML> C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML\PRTG-Scheduler.ps1

Here is the current maintenance window.

Something's wrong here. Is the PRTG Sensor still the same (i.e. updated with new entries in its comments)?

[Manimi-Chart]

That's right.

No write permissions on the report file, i.e. is the powershell script run with administrative credentials (in the security context)?

[Manimi-Chart]

When I run it manually I do not use Run as Administrator. Not sure how PRTG runs it.

I'd like to check this via TeamViewer. Could you open up a support request via support@paessler.com referring to that issue? Please state your timezone within the case, so we can schedule accordingly :)

I can confirm that this seemingly is broken in the current code. I'm currently implementing this add-on in Ruby and it will most likely be a lot easier to maintain/configure/install. I hope to have a running version in the next two weeks, please bear with me for the time being :) I'll publish it here when it's ready.
