Thanks! Checking this. Didn't try clearing cache and data, but this should be the same as uninstall/install

Maybe I'll see something using this way. Thank you very much, I need to catch this. I don't think this bug is massive, I just need to find out what's the trigger here.

Coud you give me full path - how to reproduce it?

We are unable to do it. We are trying for a long time.

Not sure if this is random Google Drive API bug or we miss something.

If you remember -did you uninstall app and install again, which option you are using when this is happening? Sync? I mean full backup, manual backup.

Please, restart phone before it to make sure gps module will re-init. 

We are saving values to text file, then we analyze it. It looks like somewhere were wrong with speed values - but it's taken from gps module so we can't do anything here. 
Everything else looks fine. If other values would be wrong - we can talk about some bug but it looks like your phone gave all the data except speed. 

But we'll see. I'll check it tomorrow also with conected to usb.

Please, record next trip and see.

Check also if you have free space on your device.

To generate speed chart we need files that are parsed. If there's a problem with space - it could be the issue.

What's also possible - just phone gps issues. Restart your phone to make sure it will boot again.

Hi. Interesting. I got Pixel 4XL and I'm using phone with Android Auto. Just checking my last trips. 

I'll check it tomorrow once again.

2 folders? 
YOu mean one /Android/ and two folders inside.

Please, try to sign out and sign in in Fuelio to Drive. Just to make sure to regenerate and clear cache for tokens.

What happened if you delete all these folders?

And then when you do full backup.

New directory should be created.

Do you use any other apps using Drive API. In Fuelio we use only strict access to files/folder. We can't read files that were saved by you, modified by you etc. Only files created by the app. If any other app got access and it's touching files somehow -we don't see it and Fuelio is creating new directory.

I tested:

If your main currency is CHF - add HRK with value 0.14 (this is correct)

Then when adding cost to fuel log or cost log - I get same values.

Which version do you use?

But wait. I just tested tihs.

What do you have in Foreign Currency.

Maybe you got more than one currency with same title?
