Error putting <iframe> in sololearn app

Question

I have tested one of my upcoming code by implementing <iframe> in its html. It works perfectly fine. But whenever, I am trying to view the output in sololearn app (android), it shows nothing. I am facing same issue with fonts too. Is there anyone who has faced same issue? Please suggest me, how can I fix that.

Answer 1

It can have several reasons.
1.) Network issue.
It is the major cause as, due to network error, page can't load further.
2.)Slow network
If network is too slow, the connection to some website is timeout.
3.) Unallowed by sites
The next reason is that, it iframe loading of some sites unallowed by those sites.to prevent their website from hacking.
If you have any other confusion then you can reply me..I am following in this post.

Answer 2

Thanks a lot for your response.
I think 3 rd point isn't my case, since i had copied the code from the iframe link, provided by the website and also it is working in sololearn web on my laptop. I think there might be a timeout issue though I am connected to a 4G network.
