Hello @Omar,
You can reply with all you want on the community, no one is stopping you, however you’re being relentless and it needs to stop at some point which is why I took the steps I did.

The problem is that we don’t have one only word from the staff. It was said that everything was ready, they were just waiting for App Inventor to release it to update too. Now, a long time later, we still don’t have any explanation of why it didn’t happen or at least an expected release date. If I was told “there will be an update only in September or later” I would be more prepared for it. but no one expected it.
I think it costs absolutly nothing for Diego and others come here and say “hi people, we are busy working with Google Ad manager system or whatever, but we promise to introduce api 30 in the next xxxx days”.

I have found solution to this problem, but unfortunately, while I was uploading modified aab file, I received following message. Can anyone suggest solution?
“Your Android App Bundle has an invalid signature. Upload again with a valid signature.”

Hi @almeidapablo,
I want to first take the time and say that everyone here has a voice, and they are listened to. Your concerns, propositions, and questions continue to make Kodular more than it was before.
Continuing, there are a few flaws in your statements that I’d like to point out, that include responses to them.
“It was said that everything was ready, they were just waiting for App Inventor to release it to update too.”
I’m sure you’ve seen, however the new release from App Inventor has major flaws. It has a few issues. Staff won’t release something that has flaws, those that are public anyway.
“If I was told “there will be an update only in September or later” I would be more prepared for it. but no one expected it.”
The problem with this statement is that even if everyone had another timeline, there’d be complaints, mainly because people are growing impatient and think November starts tomorrow… It doesn’t.
“I think it costs absolutely nothing for Diego and others come here and say ‘hi people, we are busy working with Google Ad manager system or whatever, but we promise to introduce api 30 in the next x days.’”
At the end of July, staff were telling people the API 30 release would be out shortly after App Inventor released theirs. Dismally, this wasn’t the case. People were still complaining even when they had a coarse timeline, though this wasn’t the staffs fault, App Inventor hasn’t released their API 30 release at the time.
Thoughtfully,
– Nathan

See, since the output has already been signed, I did not find it compulsory.
I don’t know if decompiling and then recompile requires signature again.
Anyways, nice guess and I will use third party app signer and then again try uploading on console. If found successful, I will be releasing full tutorial, how to do it

Please be patient and wait like everyone else. Comments like yours are unhelpful and won’t make anything happen any faster.
