If you are struggling to check in for your shift, it's possible that you are not close enough to your place of work to do so, or you do not have an adequate network connection. Make sure you're within your place of work before trying to check in and check your connection (if your location has a Wifi network we would recommend connecting to that).
If you are within your location, are connected to the internet and are still receiving the error message 'You are not close enough to check in', make sure that you are allowing Rotageek to access your location - without this you will not be able to check in.
