IOS lockdown mode

I can’t get hamrs to run with Lockdown mode enabled on my phone. No other apps seem to have this problem.
IOS 16.6.1 on Phone X.

Apple warns that a lot of things won’t work normally when in Lockdown mode. Things like configuration profiles, certain types of attachments, web sites, etc. may be problematic.

I suspect HAMRS integrates some of these features that Lockdown mode would prohibit.
