In my Excel Web (Taskpane) Add-in, the title and "Get support" in the personality menu sometimes get grayed out

Question

Hi,

I'm developing an Excel Add-in (Office Add-ins platform, not VTSO/COM), which runs a taskpane.

The add-in sometimes encounters an issue on the personality menu described below.

When the personality menu works well, it presents GoodCase.png, where

• サポートを受ける corresponds to "Get Support"
• 再読み込み corresponds to “Reload"
• デバッガーの接続 corresponds to "Attach Debugger"
• セキュリティ情報 corresponds to "Security Info"

On the other hand, sometimes it presents BadCase.png, where the title and "Get Support” menu are grayed out, while “Reload”/"Attach Debugger”/“Security Info" are valid.

Of course, the code and manifest stays the same.

Excel App version:

Microsoft® Excel® for Microsoft 365 MSO (Version 2402 Build 16.0.17328.20124) 64 bit

I’d like to dig into the problem and appreciate if anyone could give me any clue.

Thanks!
