I look forward to when this PR will be approved. Now the bot in getUpdates mode is useless. Because there is no request update, then all received requests are treated as first request.

Hi @uspilot and @yzen-dev

I see now, this is an issue when multiple requests get handled in the same session.

@TiiFuchs When you have a moment, do you see any issue with merging this? I It should be a safe fix, but maybe I'm missing some side-effect?

Checking this again, I'm struggling to see the problem.

Looking at the code in this PR and testing it on my local machine, the $command_obj already has the same Update object as $this->update, so the code doesn't change anything for me 😕

I'd greatly appreciate it if you could provide some simple command that I can test that illustrates the problem.

Thanks!

I'm not able to test this thoroughly, but it looks fine to me too.

Let's merge and test it with all upcoming changes for more fun and adventure!
