What else can gone wrong?
Do you have a git repository you can share?
I deployed the example in the downloadable zip file from How to Integrate Netlifyâs Form Handling in a React App and it works perfectly.
If you are using a built React app I have a working example coelmay/netlify-react-contact which is deployed to confident-raman-fc2e11.netlify.app.
I invited you to the repo, The template Form component is defined in the App.js. Thanks for your patience 
You still need to put the form in another file, for instance public/index.html or another HTML file inside public so Netlify can detect the form as outlined in Work with JavaScript-rendered forms. You can see an example in the repository I linked to in my previous post.

Uhh, I feel like I was a bit lame 
anyway, itâs working and I cannot be thankful enough for the patience I will recommend you
I actually have one update recommendation:
The detection system cannot read non-ASCII characters in the name of the input like: Ă©,ĂĄ,ĆâŠ
Well actually in hungarian they are very common like:
NĂ©v - Name
TelefonszĂĄm - Phone number
Kérdés - Question
It isnât a problem in the code, but the fields of the form, what I send in email should be without them so like: Nev, Telefonszam, Kerdes and it doesnât look good. Can you please ever fix this issue? I know itâs not a neccessary function, but if the dev team has free time (lol, they wonât have) it is an idea to do
Do you mean the value you are entering into a form? Can you provide an example please?
Nope not the value
<input type="text" name="Teljes nev" />
Right here in the name attribute.
Thatâs a valid feature request. Not sure if the devs will consider this or not (we havenât had many requests for this), but Iâll file one regardless.
