First, this app is amazing. I just report some bugs that occured to me.
Second, pardon my english.
1) I was just driving and at a certain point the app told me to turn right but i decided to go straight. (Note: I've enable the option in sound -> instruction level -> the 3rd one) Then waze goes sound loop 'to turn right in that specified street' with the 'please wait animation' that goes in and out. I've to close the app and launch it again.
2) Score updating is really buggy and sometimes profile page is not avaible (blank page) (I've checked my connection and I'm 100% sure everything on my side is ok)
3) Volume is generally pretty low compared to other apps.
My android terminal: arc s latest official sony firmware.
I hope this report will help you in some way.
Thanks for your time and patience and good luck with your projects
