Pinterest video Pins: wait longer for processing (or check in the background)

Pinterest video Pins fail with "video processing timeout after 60s" when Pinterest is slow, even for normal files (15 s, 1080x1920, H.264, 12.5 MB). Support confirmed the file was fine and Pinterest was still processing. Please let the processing check run longer, or keep checking in the background and create the Pin once Pinterest finishes, instead of failing the post. We post to several Pinterest accounts daily and lose Pins to this.
