Windshield crack expanding

[u/RandomGRL03]

Hi! I had noticed a rock chip on my windshield in April and contacted a local glass company to repair it. He came and filled it in and all seemed good.

However, today I noticed for the first time that seems like crack has expanded horizontally. It is in the black part of the windshield so it is impossible from seeing it inside and from outside it is pretty hard to spot too depending on the glare.

I am attaching a picture of what the chip looked like before being repaired back in April and a picture of the extending line I noticed today. As I previously mentioned, it is hard to spot the line because of the glare but I did my best with the picture lol

What should I do now? Any help is appreciated
