Is "Preliminarily reviewed" status an equivalent to signing?

I have created simple addon for Firefox with jpm.
Then I have uploaded it to “Add-on developer hub” and get status “Preliminarily Reviewed”.
I’ve got 2 new files:

  • addontest-0.0.1-an+fx-linux.xpi
  • addontest-0.0.1-an+fx-android.xpi

Linux version works good, even with "xpinstall.signatures.required = true"
Android version show the message “Firefox block installation of this addon” (or something like that)

“xpinstall.signatures.required” in Mobile version is false, but it does not work (I read that Mobile version ignores that flag)

Does “Preliminarily Reviewed” status means that addontest-0.0.1-an+fx-android.xpi signed?
How can I install that in Mobile Firefox?

I see maxVersion 43 in install.rdf, but my desktop linux Firefox has 45 and it works.
Android Firefox is 45.0
I’ve tried to change maxVersion to 53 but without success.

Btw, I’ve tried to sign addon with "jpm sign"
It requires an API key but link https://addons.mozilla.org/en-US/developers/addon/api/key/ shows me:

“Oops! We had an error.
We’ll get to fixing that soon.”

Yes. The problem might have to do with the maxVersion, which is ignored in desktop Firefox but might not be in Android. If you are still having this problem, a link to your add-on or its guid would be useful.

If you’re still seeing this, please file a bug report.
