I am on the Free plan as i just began to try out VoltBuilder.
My last upload ended with an error reporting that there must have been a network error.
So the APK was not created.
But as this was my fourth upload today, i am now blocked and have to try it again in 24 hours.
Suggestion: Inform people that “… even failed uploads count as build process.” or make those failed building productions not count.
Greetings and thanks for this nice project!
