In most cases, a charger can process your charging request within seconds but starting a session can occasionally be slower. It can take up to 2 minutes for the session to start and your app to change to enter the "charging mode". If the app doesn't sense any activity from our system within 3 to 4 minutes, it will automatically timeout the attempt, so your app doesn't get stuck.
It will usually take a few more seconds up to a minute for the app to react to the beginning of a charging session (the app enters "charging mode"). However, if that delay exceeds a minute, you can try to close and reopen the app to force it to switch. If your app is still not sensing the charging session after that, feel free to get in touch with us.
