Handy showing ? for all filaments on older android devices

Hello, weird bug for ya.

Ever since yesterday my old HTC 10 and Galaxy S5 (which has been running handy for the last 6 months wonderfully) decided to only show ? for filaments.

I have tried deleting data for the app, logging in/out, and a full reinstall. Same results ? for filament, and I can’t pick any filaments from the dropdown options.
My ‘modern’ devices behave fine:

HTC 10/ Galaxy S5 show this: (running Handy v.2.10.0):

Galaxy S9 / Galaxy S21 (running Handy v.2.10.0):
