Taxonomy Delayed Updating

[IllumiC]

When creating a site taxonomy via

$termStore = New-PnPSiteCollectionTermStore
Set-PnPTermGroup -Identity $termStore.Id.Guid -Name "ABC"

The current powershell run often does not realise that the taxonomy is called ABC.
Sometimes the importation code fails because "ABC" does not exist, but then if you rerun the same code 5 seconds later, it finds it.
If you wait for 5 seconds using a sleep action, it does not find it, which makes me believe it is an issue with the Client Context not updating, which gets updated when you reattempt.

Import-PnPTermSet -GroupName "ABC" -Path "[redacted]" -SynchronizeDeletions | Out-Null

Other times, this line fails with the error posted below it.
Waiting a few seconds and running the same line shows no error.

Add-PnPTaxonomyField -DisplayName "Subject" -InternalName "InternalSubject" -Group "ABC Columns" -TermSetPath "ABC|Subjects" -Required | Out-Null
