Hi @wanjm, I can't seem to reproduce with the steps outlined above. See the video below. Am I missing anything?

@danagbemava-nc

please use the PinYin Input method; (Chinese, Simplified, - Pinyin)
please use change your input method to Simplified Chinese

[danagbemava-nc]

Hi @wanjm, I am using the simplified keybord, see the recording below.

Can you try upgrading to the latest version of iOS to see if you still experience this issue?

I tested it on 17.1, there is no such problem;
could you please find iPad of 15 or 16, and try again.

@wanjm I don't have a physical device, I check this issue on an simulator (iPad Pro, 12.9 inch, 5h gen, iOS 16.4 - support Apple Pencil) but don't see the issue.

Can you check if this issue occurs on a native app on your device? And does this occur with different input keyboards than Chinese, Simplified, - Pinyin?

[wanjm]

1. native app don't have this issue
2. use the other input method with demo have no such issue;
3. I have tested on 3 pad , all have such issue;

simulator is different than real as big keyboard fold there is another smaller one, and the TextField is always active. but in real pad, TextField is not active after keyboard folded;

please check your video with that of mine, you will find the difference;

Thanks for checking this on native apps. Similar to #142294, I just checked this on a physical device (iPad Air 5) but still can't reproduce the issue.

I just found an issue that looks similar to this #138395. Could you try pressing Done on the keyboard instead of bottom-right button to see if the issue appears?

Press Done will not cause the issue, only the bottom-right key can cause the problem; and I think this issue is the same as #138395

[huycozy]

Thanks for confirming that. Closing this as a duplicate of #138395.
