Hello! I am having the exact same problem. I did create a model and export it with 250 inputs (images). Paid the ppi licensing for those. Then I needed to add more inputs and added an additional 230 inputs for a total of 480 inputs. Now it won’t let me export a model and gives this warning. If I start over won’t I have to pay for the 250 inputs I already paid for??? Why can’t I add inputs after exporting a model with less? Is there a way to reactivate the inputs I already paid for in a new project? Please help, as this was 2 days worth of work!!!
