I mean this please
I did not delete it

I deleted my post.
Also, I'm not trying to be mean, but please don't go off-topic - all questions are urgent. Now that we are in this topic, we should only talk about this topic. Let's focus on this question first, one at a time.
Sorry if this is mean to you
.
Dear friend, you did not do anything wrong, but I did not mean
Are you and the account who made the post you sent operated the same person? Last time I checked, making alt accounts was against the ToS.
Sorry I did not understand what you mean
Are you and the author of the topic you linked in post 16 the same person?
Edit: Sorry, this was off-topic. Should've PM'd OP instead.
No, we are on the computer, but there are two of us, one is me and one is my brother
I see. But you cannot talk about another topic in this topic. We are in this topic, so let's concentrate on one problem at a time. This is considered spam in a topic, let's focus on the right track.
All questions are urgent - we will solve them, but please be patient.
Please stay relevant to the topic. This is a community designed to get help from others, or to report bugs; not for general chatting. However, you can always privately message someone (unless you don't have the capability to do so).
I don't think this is achievable with MIT App Inventor. However, I found a Stack Overflow answer to this in Java - extension developers can try it.
Honestly, I do not know Java
If there is no physical navbar:

Thanks @Anke.
@app_inventor3 , we're not talking about that extension. Use Taifun Tools by @Taifun.
However, I'm worrying:
-
It does hide the virtual navigation bar, but at the same time it hid the status bar,
-
Not all navigation bars are virtual - some are actual buttons.
Sorry I got an error for this plugin

This is the wrong extension.
