Expected behavior

Actual behavior

There is Method not found error in vue-router

Additional information

The error occurs only on Android smartphones and when I open the sites through Telegram app.
I have tried to open the sites through Gmail Android app, there is no any errors.

I created 2 simple projects to reproduce:

• one just with vue + vue-router (https://github.com/sashtje/simple-vue-project)
• the other one with vue + vue-router + sentry (https://github.com/sashtje/vue-project) because Sentry gives more clear description for the error

This error was seen in 4.5.0, 4.4.5, 4.4.3, 4.3.2 vue-router versions. I haven't checked the others.

Struggled with the same problem in React, found out the error was caused by the Telegram WebView extension, which was trying to get your 'site_name'.

Just add a meta tag to the HTML header, and it's gone.

<meta property="og:site_name" content="my site name">
