Update hangs on download complete from 19.05 to ?

Hi,

Like many others I am also experiencing battery drain on 19.05. I dollowed all the steps that should fix this problem, but it didn't help. So I am eager to get an update. 

I checked if there were any updates available on my watch and it started downloading an update. Took a few minutes, but unfortunately the watch didn't continue to install the update and only showed the message "download complete". I already did a restart and tried to update again.

A quick search on the forum lead me to this thread: https://forums.garmin.com/sports-fitness/healthandwellness/f/venu-2/344152/update-to-15-11-stuck-on-download-successful

Could there be a corruption in the update?

I noticed that on the forum the latest version is still 19.05, which is already installed on my watch. Could this point to an issue with the update system?

Best regards,

Nick
