If the dimension size of your file is extremely large – for example a 4m x 3m banner or a very large-sized billboard, the file will take longer to process than a smaller dimension file.
To ensure faster processing time and a better experience for your reviewers when they open your proof, reduce the file in size prior to upload. For example 50% of its actual size.
If you have any concern about processing time, please reach out to our team through the in-app chat.
