"Public developer preview for Teams" disappeared.

YAMAMI Taro 6 Reputation points

I am developing an app for Teams meetings.

I know that I can enable the developer preview by allowing tenant to "Enable custom Teams apps and turn on custom app uploading" as described on the following page.

Enable developer preview
Enable custom Teams apps and turn on custom app uploading

For a while, the "Developer Preview" was working fine.
But suddenly the "Developer Preview" menu disappeared.
I haven't changed from the settings "Enable Upload custom apps", and I can upload without any problems.

How can I get the "Developer Preview" menu to reappear?

App for Teams meetings cannot debug it in the browser.
It is difficult to debug because I cannot switch to the "Developer Preview" menu and I cannot open the "DevTools".

    Could you please update the Teams version and check again?
    Could you please update the policy as 'Not Enabled' and check again?
