I only view push notifications on my phone with Pushover.net app, can also use Slack or Teams, both should work similar. If I must do something on Syncro from my phone, I typically log in on the browser and use the mobile aspect of the site, the rest I do on my laptop. But, yes, the app is past due for an update.
Import-Module $env:SyncroModule Add-AppxPackage -Path "https://github.com/microsoft/winget-cli/releases/download/v1.0.11692/Microsoft.DesktopAppInstaller_8wekyb3d8bbwe.msixbundle"
and then
winget install Microsoft.Teams --silent
