["? cracked" instead of font name]

In Affinity Designer for iPad v1.6.4.45 I activated the setting to import text in PSD files as text instead as Pixel layer. I then opened a PSD document with a text layer that uses a font I haven't installed on my iPad. When selecting said layer now and switching to the text tool, instead of the name of the (missing/replaced) font it says in red "? cracked".

I would expect at least a warning on opening the file that a used font isn't installed and maybe let me choose then between replacing it with a default font or importing affected layers as pixel layers instead.
