Why did I get duplicate messages?

In short: it's almost always due to a slow computer or a slow connection. A few simple steps fix the vast majority of cases.

💻 Why it happens

When the computer struggles (an older Windows or Mac) or the internet connection is slow, sending can sometimes get duplicated. These aren't duplicates intended by Novalya.

🛠️ What fixes 9 out of 10 cases

• Restart your computer — we do it too rarely; it clears the accumulated cache that slows everything down.
• Close other apps and tabs, let Novalya run on its own.
• Disconnect then reconnect Novalya, Facebook and Instagram, and relaunch the extension.
• Enable the anti-duplicate option (built into Novalya).

💬 Good to know

These small technical glitches can happen occasionally, without consequence. However, if they recur regularly, let us know: we want to know and we'll look into it.

✅ 30-second checklist

• Computer restarted, other apps and tabs closed
• Novalya / Facebook / Instagram reconnected, extension relaunched
• Anti-duplicate option enabled
• It happens often → write to us

❓ FAQ

"I sent the same message twice to someone."
It's almost always a computer or connection slowdown: restart the computer and check that the anti-duplicate option is enabled.

"Is it serious?"
Once in a while, no. If it's recurring, report it so we can step in.
