I don't know of a way to give you a firm answer and will have to suggest you use common sense:
-if it's a 'fixed' document that cannot change (eg copy and trans of birth certificate), should probably be okay.
-police certificate: definitely update.
-any doc you can update yourselves and you sign (eg forms): must update. (General rule: three months max)
-if it's an official or signed doc that has some legal meaning that could potentially be revoked (eg permission from other parent), must update.
You'll have to use your own judgment. Apart from their own docs and forms, I'm not aware of a specific instruction.
You can also include a short letter of explanation that process long in Colombia and eg if any need to be updated, you will provide as soon as possible. (This won't be a magic defence against having the app sent back though)
