Issue resolved by email
The solution consisted in:
– moving some images used early on in the experiment, from a zip file on the S3 bucket directly into the Resources folder of the project, so that they could be fetched independently from the requests to the S3 bucket
– splitting a big zip file (~400MB) in two smaller zip files
– optionally moving the CheckPreloaded trial later in the experiment, in order to give PennController more time to download the zip files and preloading the resources in the background before reaching that screen
