Streamlit working on web browser (not mobile)

Using Streamlit
1

Hello everyone!

Amazing tool! Love what you guys did.

After building and deploying my app to https://playground-ml.herokuapp.com/ I came to notice that it doesn’t open on mobile browsers (specifically IPhone when using Safari and Chrome) : when you hit the link, you’re faced with a blank page (not even an error message)

Could this be related to Heroku?

It’s hard to debug on mobile. On desktop, everything works fine. Has anyone faced this issue?

Thanks for your help.

Hello @ahmedbesbes, welcome to the community! And what a nice app you have delpoyed there :slight_smile:

On my side your link works perfectly on iPhone Chrome and Safari though, I’ve been able to change dataset and play with the sidebar parameters. Did you change anything in between?

Cheers,
Fanilo

Hello @ahmedbesbes ,

I had the same issue. My app worked on web browser, on some mobiles but not on all mobiles.
I solved that by taking a previous version of Streamlit (0.74.0 in my case).

Hope it will help you.

Hi All,

Even my application was not launching on iPhone earlier then I tried with Streamlit (0.74.0), it worked for few days and it’s not working again.

Application loads on iPhone and it gives me Connection error - connection timed out.

I’m seeing this as well. It works in the browser but not on the phone. Well, it sometimes works on the phone. It seems to work once and then you have to reboot the phone. Same inconsistent behavior on multiple iPhones.

Hi. It seems that this issue is still giving problems, at least to us. Any news? Adding the port to the config.toml does not solve the problem. And it makes no sense to me to downgrade from streamlit 1.30 to 1.8 at this point.

Please advice.

Have anyone found any solution for the above . streamlit app is working in web browser and mobile browser. but when i try to render on webview of android through rendering it doesnt show any

Hi, I am having same issue, specifically since I wanted to turn my streamlit app into an android app, by using webview to display it. The app is hosted on heroku, it shows well on desktop and mobile browsers, but the webview specifically shows nothing of the app’s content (it shows streamlit top colored lines + the topbar with the arrow and 3 dotes, but nothing else below). I tried a few approchaes, to change versions etc… but not work. Would adding the ?embed=true to the url do something? Do you have any suggestions as to how to solve?
