The study was mobile only. I opened it on my phone, the second question asked what was the OS of the device I was taking the study on and I selected Android. I was immediately sent back to the Prolific screen and was given an auto rejection with no reason. No response from the chat.
I currently have 6 studies all about this but only for desktop/laptop/tablet only. I avoid those that ask for face cam and voice recording, especially pays for cheap
I canceled as soon as I saw it translated the page from Russian to English.
