Uncaught TypeError: undefined is not a function

1

I get following Error on my Android 5.0 AND Android 6.1 device using Framework7 Version 4.5.2:

Uncaught TypeError: undefined is not a function (framework7.bundle.js:4315)

The line 4315 inside Framework7 Version 4.5.2:

Object.assign(Request, {

Notice:
The Problem is the Object.assign so I used this polyfill: https://gist.github.com/spiralx/68cf40d7010d829340cb

But now all the ajax requests timed out (timeout). What do I have to do?

I would suggest your devices have outdated webviews. You can’t rely on these old androids. I would suggest to target Android 7+ for Framework7
