Fuel log and mileage tracking app for Android

How reminders works?
Sorry for being so stupid but I didn't get how reminders works. I set up reminder for a certain day. The day has come a nothing happened :-( No push notification, nothing when I started the app. So what is the reminder for?
I also didn't find a way to show list of reminders. There is no option in the menu :-(
Can anybody give me a tutorial how should reminders works and how to be notified when it reaches the day / odometer state ?

Trip does not end after disconnecting from car (auto-launch feature)
I started using auto-launch and for most trips it works perfectly OK - trip starts when phone Bluetooth connects to car and it ends when Bluetooth is disconnected. However, despite "start" works reliably, the "end" does not - on some occasions the trip continues to be "in progress" and it only finishes with the end of the next trip. There is even no way to finish the trip manually (it does not show in notification center).

How to reset gas milage stats for one of my vehicles?
I have a car I am modifying and want to see if my gas mileage improves. Is there anyway to reset the MPG stats for this vehicle and leave my other intact?

E10 missing from 'Fuel type' selection
When changing settings for the overview of nearby gas stations in the main menu, there is no option to select the fuel type 'E10' offered by all major German gast stations.
Am I doing something wrong, is this intended behavior or did I discover a bug? I would be happy to provide more information if required!
Thanks!

E10 is in Ethanol group. To use petrol+ethanol on one tank go to vehiccle section and select Flex (type)

I entered a recurring cost , how to modify it or delete it
Hi, I entered a recurring cost, the app can auto input those information. By now, I need modify the cost amount. But I can not find any way to modify it or stop the recurring cost.

Missing entries
Last week I was checking for old entries after a long trip. Yesterday when I was trying to the same, I noticed 3 months of entries were lost. I checked on Google Drive and local back up and the information is missing in all of them.
is there a way to recover it?

Fill limit
I created a csv file with more than 300 lines and exported it successfully to Fuelio. Now, surprisingly, I only have 100 fillers. Is there any fill limit for Fuelio? Greetings, Fernando Pinto

Could you please add "E20" to the Fuelio?
This fuel type is using in Thailand. In Fuelio has only E22 and E27. Could you please add it?
Thank you very much.
