No signal

The engineer app needs a connection. When you lose signal you’ll see You’re offline — reconnect to continue at the top.

• What you’ve already saved stays saved.
• Taps that didn’t go through are safe to try again. Sustainable ERP never records the same step twice, even if you tap more than once.
• Photos that didn’t upload show Failed · Retry. Tap it when you’re back in signal.

If you’re somewhere with no signal for a long time (a basement plant room, say), take your photos and write your notes, then step outside to finish the job.
