I cannot get the Gasbuddy App to run on my 635. It was working fine and has now quit. I uninstalled and reinstalled it twice. Still doesn't work. Any suggestions? Thanks!
I have no dedicated fix but some of below tips may help.
After uninstall go to Storage Sense and delete "temporary" files, do a soft reset, switch on and off after uninstall, try install it on the internal memory and not on the SD card.
And contact the developer of this app maybe they can help you out.
seems to do it on lumia 640 too. guess the app is having trouble and needs to be updated. could only get it to work if using wifi. will not work using data.
