Thanks in advance for any feedback.

Sentinel 1 acquisitions on the same track over the same area at successive times (12 days apart) the one swath is skewed. Seems as if the skewing started in July 2019 and ended by February 2020. After February 2020 the swaths went back to being rectangles like they were before July 2019.

I’m hoping someone can help me since this seems to be the cause of my time-series sub-regions being misaligned. Is this likely to happen or is this a problem with the meta-data in the acquistrions?

The acqusitions are aligned just fine. If you compare these two dates in EO Browser, you will see, that locations match:

I am therefore gussing that there is some problem on your side.

If you have questions related to SNAP, I suggest you ask at their forum:
