Very interesting bug.....

it's not possible for the export mechanism to generate screenshots using stale data because:

On Screen:
app-db -> load img assets -> compose -> draw to on-screen canvas

Export:
app-db -> load img assets -> compose -> draw to off-screen canvas -> export to jpeg base64 -> create screenshots.zip file

Downloading the zip file:
if browser supports <a href="..." download> -> use FileSaver.js
else -> upload zip as skygear Asset and inject hidden iframe into the DOM with asset URL

If this is not a false report I guess screenshots.zip is being cached somewhere....
what do you think @b123400

Safari started supporting <a download> from version 10.1 (latest version) so I can't test the fallback download mechanism.... and we all know how hard it is to downgrade Apple's stuff....

FYI the issue happens on:
macOS Sierra v 10.12.4
Chrome v 58.0.3029.110 (64-bit)

@david90 Can we get QA engineers to try reproducing this? I can't seem to reproduce it...
