A potential issue with the campaign could be that one of the source files is in WAV format.
- One of the ads is missing a companion creative.
- One of the source files is in MP3 format.
- One of the ads was created in Ad Canvas.
- One of the source files is in WAV format.
The correct answer is: One of the source files is in WAV format
Explanation: Display & Video 360 allows for the direct upload of audio creatives and the assignment of existing display creatives as companions. However, it only accepts .ogg and .mp3 file formats for audio creatives. If one of the source files is in WAV format, this would not be accepted, leading to issues with the campaign’s execution. It’s crucial to ensure all audio files are in the supported formats to avoid such problems.
