Sure!

And
"@ckeditor/ckeditor5-vue": "^7.2.0"

Hmm, we fixed similar problems last year, could you share as well the Android version, phone type, and ideally the keyboard type you are using? Thanks!

(I got this problem from multiple clients(devices) so it's not one specific device issue)

Very urgent for us :/

[greeto]

Any news/ideas maybe? becomes really urgent for us :/

Hey, we usually don't hastily improve the typing pipeline, this is a very complex matter. We haven't got more requests like that, so we need to pinpoint the cause, and we will be investigating that.

Hi, I'm not a premium customer, but if I will be, will it make it faster?
Also, how do I become a premium? @Witoso

So far we couldn't reproduce the issue.

Steps we took:

1. Use the WebView Android app.
2. Set up a Vue 3 app and create a CKEditor 5.
3. Visit the page in the WebView.

We were unable to replicate the issue that was reported with duplicated typing. Could you share some reproduction methods we can use?

[greeto]

Hi,

1. Can you share the Webview code you did please?
2. Here's the base of the Webview I'm using: https://pastebin.com/g4QJLTez
3. Android Device Emulator: Pixel 3a API 32 arm64-v8a (Android 12)

We didn't create a webview, we are not experts in mobile development :). We used a proxy app that you can test as well (WebView Android app).

[greeto]

Thanks.

I've opened some debug logs and now I see some errors related to CkEditor while I'm typing:

Ok I got the error solved somehow!
Seems I used some custom 'user agent' on that webview but it caused CKEditor throwing errors.
So I've disabled that now and it got resolved.

[Witoso]

Good catch, based on the environment the typing may behave differently as devices' input methods are not standardized. AFAIK, we use user agents to detect the environments.
