Hmm.. If you can please send me report (after error) with your name. This could be tricky to debug. 

You can't click on choose account button? 

Do you have custom rom? Do you have Google Play Services installed? Do you accept Google permission? 

Thanks i dzięki :)

Yes. I know about that. This is connected to Fuelio CSV format. I'll think about that - how to change the format to be compatible with the previous versions.

No problem. Remember about GApps when installing your custom ROM (specially CM).

You could also change your ratings. Maybe now Fuelio is worth more than one star ;)

I need to create some info when you are adding first fill-up.

First fill-up is initial and you need to enter odo counter value. From now, you can use trip counter and everything should be OK.

You need to edit your entries. It's easy to fix.

Hi,

I don't know your mail but you should know my :) Please, send me your CSV.

You'll find my mail at fuelio.mobi page or Google Play Store page: adrian.kajda+fuelio(at)gmail.com.

If you have PRO version you should be able to swipe right and see Cost module.

Yes, of course. Like I said before. My mail is on fuelio.mobi page.

Hi,

1) To use Pro functions you need PRO key installed in your system. That's it. Nothing else. Don't uninstall Fuelio app (the free one). If you have Fuelio and Fuelio PRO in your system you can run fuelio (main app, not the key) and you'll see additional features. 

2) Yes. Send me your file

That's strange. Your log should be sorted by date and odometer. Maybe you've got error in your log. You shoudn't have newer fill-ups with lower odometer values.

Sorting order is ODO and then DATE.
