Get individual digits for short year (#Dyy#)

I want to split the short year value, i.e. #Dyy# into the individual digits.
Seems simple to do:
1st digit: (floor(#Dyy#/10))
2nd digit: (#Dyy#%10)

This works fine in designer and for the preview in the Facer app on Android.
It worked fine on my watches as well before the “upgrade” to WFF.

Now my Samsung Galaxy Watch 6 Classic running One UI 8 (WFF):
always returns 0 for (floor(#Dyy#/10)) and
always returns an empty result for (#Dyy#%10)
(#Dyy#) on its own does work.

Doing the same for the month value, works as expected.
(floor(#DM#/10))
(#DM#%10)

I.e. I only have the issue on the physical watch device for the year value.

This seems like a Facer bug to me.
Can anybody else confirm this?

BTW:
I tried to report this bug to Facer on 16 December 2025 via email (support@facer.io) but am still waiting for a reply.

I normally use the support page at https://help.facer.io/hc/en-us/requests to submit support requests, but am unable to sign in there: “Couldn’t sign you in. Give it a moment and try again.” First noticed this on 16 December 2025.
I sent 2 messages to support@facer.io regarding this issue (16 December and again on 5 February 2026) but have not received a reply from Facer yet.
I.e. I need support regarding Facer support… :crazy_face:
