You must run the application inside Telegram. In case, you are still having this issue, please, create a reproducible example.

I have just checked using the template this way:

1. Press the Use this template button and create a new repository on GitHub.
2. Go to the Vercel dashboard and add this repository.
3. Use a default Vercel configuration for the Next project, deploy the project
4. Create a new app in BotFather and specify link, returned by Vercel
5. Open the app

This worked fine for me, I used only GitHub and Vercel interfaces, zero configuration

To launch an application for local development use some tunnel, like localtunnel and put url in botfather settings.

My user faces this issue in the Telegram web view; after refreshing multiple times, it returns to normal.

Device: iphone 16 pro OS: ios 18.0.1 Telegram version: 11.3 (29835)

What could be causing this issue?
