Apple bark issue, squiggly lines

Hello everyone! I’m trying to ID a bark issue that I’m seeing pop up in several of my apple nursery trees. Some info on the plants: 2-3 year old trees on bud118 and dolgo rootstock.

It starts out looking like this- long squiggly lines on the bark.

This is it in a more advanced state.

Some trees are also showing this vertical cracking, I’m not sure if it’s related but I feel like it may be.

Any thoughts? I’ve had a hard time IDing this through various forum searches, online extension resources, etc. Anthracnose? Winter damage? Pest? Would appreciate any insight into this!

The bottom picture with the vertical cracks looks similar to cicada damage.
