Learning track lag

For written responses in the learning track, it is taking way longer than usual to correct, which, after like quite a while it still hasn’t been corrected. I eventually gave up waiting and reloaded or skipped the question, but I have never gotten my response corrected. And it doesn’t matter how long my answer is, could be one word or a whole paragraph they just don’t load.

I wonder if it is my network problem or is there a little bug or lag
