I use this DF: https://apps.garmin.com/apps/1457cf5b-bf18-4db2-8d26-220c773322cb
I have it installed from before it became monetized, so I have a free version installed on my fr965.
I haven't used it for a while, but this week I did use it a few times, and each and every time I only see an IQ... icon instead of the DF.
There's no CIQ_LOG file in the logs directory.
We think it might be somehow related to the fact that the app was recently turned to be monetized.
fr965 FW: 23.20
