[BUG] Pnp-term commands on pinned terms issue

Reporting an Issue or Missing Feature

Issue

Expected behavior

Move-PnpTerm on a term that is pinned in another termgroup should move the term to the destination
Set-PnpTerm -deprecate should set the term to deprecated

Actual behavior

got an error message : The operation is not valid on the pinned term

Steps to reproduce behavior

Pinned manually a term to another termgroup and try to use the following command:
Move-PnPTerm -Identity -TargetTerm -MoveToTerm
Set-PnPTerm -Identity -Name -TermSet -TermGroup -Deprecated $true

What is the version of the Cmdlet module you are running?

I tried 2.2, 2.12 3.1

Which operating system/environment are you running PnP PowerShell on?

• Windows
• Linux
• MacOS
• Azure Cloud Shell
• Azure Functions
• Other : please specify

I’ve many terms in a Termgroup that are pinned to another termgroup. Using PnP cmds on those pinned terms result to an error message: The operation is not valid on the pinned term
I can understand this limitation, but this behaviour is exclusive to one of my 3 tenants and seems to imply we basically cannot do anything an a term at the moment it's pinned somewhere else.

Authentication method : interactive or by apps & certificate
When I remove the ‘link' to the terms from the secondary termgroup, it’s working as expected.
When I recreate pin, the issue come back.
Structure of terms, Ids, Name, creation method, pinned method are aligned on all 3 tenants.
Doing it via graphical interface is working well

I would like to ask for any help or similar experience related to it in order to identify the cause and avoid the same behavior to be propagate in my others tenants

Thank you in advance,

Start by reproducing the Move-PnPTerm and Set-PnPTerm commands against a term pinned in another term group, comparing the failing tenant with the tenants where they work. Trace the command entry points and the handling of the “operation is not valid on the pinned term” response; done means both commands support the reported pinned-term cases without breaking existing behavior.
