Is there anyway to show the complete 30 day sinch instant messaging historic on android without have to wipe the app data? It seems that once I read the messages there's any mechanism that says to not show them again. Is there any way to prevent this? Thank you in advance
No, sinch is not an inbox, we keep the messages for delivery for 30 days to each device. If you want to keep messages in a login / logout scenario you need to save them in your own backend.
