Tha icon ultimate is a project i was part of a long time ago (2012-2013), this was before i had my own google developer account to work independently. At that time i was relying on charitable soul to help me get some icons out there.
The app developer account was not mine, im Tha PHLASH not Jon Hancock so basically i was only licensing my icons. But they were not my personal apps codes or my google developer account, just my art.
In the case of Tha Icon Ultimate, my guess is since the app stopped been developed a few years ago, and we also have stopped accepting payments for a whole year beforehand so that the last person buying a token had 1 year to download the icon they wanted.
Its also good to note here that Tha Icon Ultimate was not made to download whole packs but rather individual icons one by one. A old technique used in android in the early 2010’s. This is also why that app was been phased out in favor to having traditional icon packs.
So when the app stopped i think Jon kept it open another full year afterwards but the external servers that were somehow left open have finally expired?
There’s no refund for anything related to this project, since its not the owner of the dev account i do not have access to your individual receipts either. But i hope this answers most of your questions.
