There’s clearly some kind of delay/compensation/shift on the audio track at their end. Is it still there when they export or is it just during timeline playback? Does the sync shift over time or is it all out by the same amount?

It seems to all be out by about 5 frames consistently (although the ads are all like 20 seconds long). I don't think it's a sample rate drift issue as there are musical sounds in there and I'd hear the pitch difference.
They sent me a screenshot of the Premier project and can see an extra block of silence in premier's weird waveform display at the start compared to their reference, so it's in timeline playback as well.

Bringing up my sound to video woes again as we've ruled out a bunch of issues, but still at an impasse.
If I export my audio, to their video, and put them together in Premier, then the audio is totally in sync. I have sent them an exported video demonstarting this.
If I give them my audio, and they attach it to their video, they say my audio is late, and it is - although the audio file is still the exact same length as the video.
They are now telling me to maybe cut 5 frames of audio off the start of my audio tracks. This sounds like a very dangerous idea. Clearly the problem is their end?
EDIT: I should add, in case I haven't done this already - this is not for TV ads so whatever standards are at play there are likely not relevant here. It's for online ads e.g. ads before YouTube videos, in-app adverts etc. I expect there are few if any accepted av standards in such adverts.
