Hi! I found an issue when running background timer in any app while having custom watchface app on Forerunner 55.
After background timer is done and accepting to go back to the app, there's CIQ error screen. On release apps, nothing is appended to /GARMIN/APPS/LOGS/CIQ_LOG.YML.
After I created debug version of BackgroundTimer example from ConnectIQ SDK and my custom watchface and accept after background timer is done "Signature check failed on file: ._BackgroundTimer" error is appended to CIQ_LOG.YML file.
When having one of the default watch faces, problem doesn't occur (see the video on YT: https://www.youtube.com/shorts/JPNk14yJBRU - first is with system watch face and then triggering CIQ error after changing to custom watch face)
I tried this with different SDKs (4.2.4, 6.4.2, 7.2.0, 7.3.1 & 7.4.1) on Forerunner 55 with 10.01 & 11.01 software version.
