Error: you must choose a build

Hi! I'm newer in App Store connect and I'm trying to upload my first application on App Store.
I've built my application and uploaded it on App Store Connect through XCode. Now it is in Activity tab with status Processing. When I go to App Store tab under Build section I have the following message: "Upload your builds using one of several tools. See Upload Tools" and I have no button + to choose my build. The button on the right corner "Submit for Review" is active but when I click on it it shows me the following error: "Unable to Submit for Review: You must choose a build".

Can anyone help me, please! What is wrong? What I'm doing in wrong way?

I also have the same issue. Is there anyone with a break through?

You have wait for the processing of the app. It´s depends of the binary´s size. Here is more information about the different status.

App build statuses

I uploaded my app to App Store Connect through the Transporter app. Afterwards, under my app, I clicked on my app and the build option was available.
