Thank you derek87! I now have a report submitted for this disruption.

Thank you for your participation in this forum thread. So that I may assist you further, please reply with the following:
Hi Garmin-Kevin. This is already the second time that I am asked to participate on bug hunting by giving permission on a public forum and then potentially go through the cumbersome process of copying all 955 memory, and then manual delete the maps *.img files before upload.
Given the current state of constant bugs, wouldn't it make sense for Garmin to invest on some more automated way to collect telemetry?

kalamarios I am happy to assist in whatever way that I can. I am required to ask for permission to contact and to access/view user account(s) for each individual interaction/reported disruption. I understand that this may feel repetitive to you and I apologize for the redundancy. We do things this way in an effort to give you control of your privacy.
If you seek some other way to report disruptions and seek assistance, we also encourage you to reach out directly to your local Garmin product support team.
