How do I get Google Maps location sharing notifications on my second device

**TL;DR:** With two Android phones, how do I get arrival & departure location sharing notifications on my backup device, instead of the primary device? ---------- I have a primary and a backup Android phone. Recently, the primary one developed an issue with the display, rendering it mostly unusable, except with screen projection utilities (e.g. AirDroid and scrcpy). As a result, I switched to using the backup phone. Over the last couple of days, I noticed that Google Maps was still sending notifications of arrival & departure (notification channel: *Google location sharing (friends)*) to my now unusable primary device. After searching the internet, I found [this answer](https://support.google.com/maps/thread/286527280?hl=en&msgid=286627449) , which essentially requires me to sign out of my Google account on the primary phone. This solution is untenable for me, as I intend to repair and return to using the primary device in a couple of weeks. In the meantime, however, I still want to receive notifications on the backup device. How do I achieve this? Here are the things I've tried which didn't yield the expected result: * Fully disabled location sharing on the primary phone * Disabled all Google Maps notifications on the primary phone * Cleared data and disabled Google maps on the primary phone * Disabled & re-enabled location sharing on the backup phone
