This is a known issue with Amber + some newer apps. A few things to try:
1. Clear Amber's cache (Settings → Apps → Amber → Clear cache), then try again
2. Make sure Amber is set as the default signer: Android Settings → Apps → Amber → Open by default → enable "nostrsigner" links
3. If Shosho is sending a large event (like a long post), the intent can time out — try signing a shorter action first to confirm the connection works
4. Check if both apps are updated to latest versions — older Amber versions had bugs with certain event kinds
5. As a workaround: copy your nsec into the app directly (less secure but bypasses the signer issue)
If it keeps buffering, it's likely an Android intent timeout. Some phones aggressively kill background processes — check your battery optimization settings for Amber.
