Since the update to 19.09 my audio prompts act haunted. First i lost them completely. Then I started activity and All prompts from the last 2-3 activities started playing one after another until the end. Then theu worked for the first few minutes (pace and HR Zone prompts configured every 2 minutes) and stopped again. Currently the behavior is similar - they start Ok and stop after the first 2 minutes.
Tried force stopping garmin connect and clearing its cache to no avail
