Thanks!!

Updated to 63.0.3239.111 and confirmed.
The occurrence frequency fell, but it was not completely corrected.
The frequency of occurrence fell from 90% to 40%.

I confirmed that this does use a webview. Paul, could confirm the bug? Is this a known accessibility change?

Typo, I meant to say "could *you* confirm"

I get no repro with shamu, Android N2G48J, TalkBack 5.0.4, WebView 55.0.2883.91 or 63.0.3239.83, after several attempts.

Questions for harumiyu2317:
- What TalkBack version do you repro with?
- It might be helpful if you attach an adb bug report taken after repro'ing the bug.
- When you say "the Accessibility Event from Chromium was not notified", does that mean you've debugged this yourself and looked for ax events in the code, or do you just mean you don't see accessibility working in the GUI? If the former, can you describe your investigation?

>- What TalkBack version do you repro with?

->
I was using 6.1.0.186797687.

>- It might be helpful if you attach an adb bug report taken after repro'ing the >bug.

->
As a result of checking at 65.0.3325.109, no event occurred.
I reconfirmed it at 63.0.3239.111 where the problem occurred, but it also stopped occurring here.
Because the content has changed, logs can not be acquired.

It is the result of debugging by yourself.
We added a log to requestSendAccessibilityEvent and confirmed it.

After updating to that TalkBack version, I still get no repro, after several attempts.

Do you know, what's the last good WebView version before this bug appeared?

> Because the content has changed, logs can not be acquired.

Do you mean the docomo website has changed, and now you can't repro either? If so, then there's probably nothing we can do.

>Do you know, what's the last good WebView version before this bug appeared?

 confirmed that there was no problem with the version number of 62.0.3202.66.

> Do you mean the docomo website has changed, and now you can't repro either? If so, then there's probably nothing we can do.


Yes. It seems that the content of docomo has been changed. Comparison is impossible because there is no past content.

Please let us know if you find another way to repro.
