Should I disconnect and reconnect if something is missing?

In short: only with care.

If a single activity is missing or hasn't shown up after ten minutes, that's no reason to set up the connection again. In most cases the session catches up on its own – in the worst case it takes a day (see My activity hasn't shown up in Trait). Frequent disconnecting and reconnecting strains the connection to your provider, and at some point it stops working altogether.

When reconnecting makes sense: If two to three sessions haven't arrived within about a week, something is probably wrong with the connection. In that case, proceed as follows:

1. Home screen → Settings → Connections
2. Disconnect the affected connection.
3. Set up the connection again and confirm it with the provider.

You make up for individual lost sessions by manually marking the planned workout as done in Trait.
