How long does it take for L1A to extend? (Standard)

I’m currently renewing an L1A visa from inside the US, and the timelines are incredibly slow.

I understand standard processing has slowed down significantly due to high scrutiny and backlogs. It took 2 months just to get the I-797c receipt notice for me.

Is anyone else experiencing this extreme slowness with USCIS for their renewals right now? How long did yours take?
