I also have this bug now, that occurred on other Forerunner models. Didn't find it in the 945 LTE forum yet.
Daily Suggestions have no entry for today and there's always rest day for tomorrow.
I think it was triggered by deleting an event on Garmin Connect web.
I'm on 17.30 and this workaround didn't fix it for me: https://forums.garmin.com/sports-fitness/running-multisport/f/forerunner-255-series/354514/training-suggestions-only-showing-rest-day/1708503#1708503
Garmin-Sierra Any chance of getting this fixed also for the 945 LTE?
Are any other of you 945 LTE users also affected?
