Importing libraries on iHP48 for iOS

[Ox49+]

Anyone have luck in importing libraries to the iHP48 app?

I've downloaded a few libraries from HPcalc.org.
I moved them into the iHP48 folder on my phone with the Files app and unzipped them there.
When I use the "Load Object" command from the iHP48 menu, the library file gets dumped on the stack as a string (at least that's how it appears).

The string starts with "HPHP49-C" but doesn not contain the normal library prefix/number.
Is there a trick I'm missing?
Is there an issue with the way the app imports binary files?

I'm mainly using the HP 49G+ emulation, but I tried with the HP 48 ROM as well.

Thanks in advance!
