I have just RAISED a support ticket as encountering exactly same problem as no categories downloading
Hi. Yes I'd like you to raise a support ticket to walk you through raising an environmental report - this is currently an open forum that you are posting in and everyone can see and the originator will receive notifications. So better you have your own ticket direct with our support desk to work through your unique situation. If you can please email email@example.com then this will create a support ticket. Please tell us in that ticket/email which app you are using and on what device. Then we can get you working.
I haven't seen a ticket relating to this for you. Can you raise a support ticket please? Also ensure that you have a data connection with credit and location services turned on.
Can you raise a ticket concerning this as the app appears to be working fine currently and so may be specific to your location or settings. Please check you have location services and a working data connection and if still seeing an issue raise a ticket please.
Love Clean Streets Support
