I have tried to solve the issue of the Instagram in-app browser on mobile not rendering the full page. I am hosting & deploying through Netlify, and tried to change the CSP via toml file to ensure that there is nothing blocking there but this didn't help. I also don't have any redirects in the file so nothing seems to be wrong in that matter. I am thinking of forcing to not use in-app browser, but it seems not to be recommended. Anybody with that issue? What would be the possible solution & the best solution?
