The upcoming release of Avenza Maps v3.2 for iOS and Android includes a critical update that requires your attention.
Dropbox has released a new API for external apps to connect to. We have updated from Dropbox API v1 to API v2 in Avenza Maps because Dropbox will shut down API v1 on June 28, 2017. It means that earlier versions of Avenza Maps may not be able to connect to Dropbox after this date.
To ensure uninterrupted service, you should upgrade Avenza Maps at your earliest convenience when it is available starting June 6, 2017.
