If you would like to request a change to the external online build server, you are welcome to go through the full process of submitting a feature request as described here: Welcome to the User Feedback channel!
Keep in mind the external online build server is not part of the engine itself. It is an external service offered by the gdevelop company, it is linked in the export panel as a convenience feature for folks, with increased builds amounts per day for folks who subscribe. The size limits could change at any time, and the details I provided above are available all throughout the forums.
Additionally, we still need the actual original poster to confirm if that is actually the issue they are having. So please feel free to go through the proccess above if you would like to request something, but it isn’t really relevant to this thread.
