There have been reports of items that were forwarded through the GSP during the pandemic just "losing" their tracking information until a couple of days before their delivery.
My advice would be to forget anything you know about the tracking or lack thereof of your item and focus on the estimated delivery date. I would say that given that the delivery turnaround was estimated at a month, there were attempts made to make allowances for the general state of chaos out there right now. I'd probably give the item another week or so before filing a claim of non-delivery.
