We have an Import Customer automation which runs every hour via SFTP file drop - FileName Pattern SFMC_CUSTOMERS_10312023040011.csv and populates our customer DE. We have another file drop automation running for a birthday campaign - Filename Pattern begins with SFMC_CUSTOMERS_BIRTHDAY_1102201340001232.csv
Whenever the campaign file is dropped, it is being picked up by the Import Customer Automation instead of the birthday campaign. Has anyone faced a similar issue?
How can I avoid this from happening, any priority I can set apart from changing filenames.
