Missing "Evidence of Invitation" from the Upload Documents

BringItOn

Hi,

Naglodge na kami ng Visitor Visa 600 (tourist stream) for my mom, then expected ko merong "Evidence of Invitation" sa upload ng documents para iprovide ung Statutory Declaration, pero walang lumabas. Ask ko lang kung merong the same case ba dito? Also, ilang beses ko na binalikan ung form pero wala ako makitang kakaibang tanong na pwedeng mgrequire nito. Dun sa Fund for Stay na portion, nilagay namin Sponsored by Others, then Child ung relationship, then All Costs.
