I have to stick with the same plugin version, especially since I already have some apps exported using it. ---

I found the cause of the problem. Yesterday, after 6:00 PM, my application stopped working on my main account. I believe this is because I used up all my API tokens by mistake. I have an application running in a museum, and it is currently not working. I know this application doesn’t use the API directly but use only “Interaction Usage”, and when my account runs out of API credits, all of my applications stop working. Is this a bug, or is it intended behavior? If it is intended, can I buy more API credits so that my application works again as soon as possible? This is extremely urgent, because the museum is open today and the application is currently down. Thank you very much for your help. Kind regards, Bixer ---

I’m not sure how it happened, but I fixed the issue by logging out of my account and logging back in. The new application now works exactly as it did before. However, my older applications no longer work. I suspect it was some kind of bug. Could you please look into it? I have applications installed in museums, so I need to be sure this won’t happen again and that the older apps can be restored. Thank you very much for your availability and support. I look forward to hearing from you. Kind regards, Bixer
