Indexing problems

I’m in charge of writing and posting articles on the start-up’s website
Since October, we’ve been experiencing problems indexing our pages. All the articles I’ve been publishing lately are not indexed. Most of them have “correct canonical tag” as a reason. Google refuses indexing when I request it.
Our development team has looked into the matter but can’t find the source of the problem. We’ve looked at the coding of our pages, but there doesn’t seem to be a problem. What’s more, we write our articles by hand.
Can you please give me a solution and tell me the source of the problem?

Thanks in advance

@Melissa_Malolepszy - I would start by fixing your canonicals’ since many of them are pointing to which is redirected to which is serious issue that can affect how search engines crawl and index your site. If you need professional assistance with SEO feel free to reach out via a DM.
