The data displayed in the investor portal is tied to the account to which the allocation is linked. If you cannot locate a particular allocation in their investor portal, it's probable that you have made contributions using different accounts.
By signing in to the specific account associated with an allocation, you should be able to view it in your investor portal.
If you have made contributions via numerous accounts, the sole method for you to unify all your investments within a single investor portal is by transferring your allocations to a single account. Only a platform administrator can move allocations between accounts.
