Did you do an OTA download or did you download the jar file from here and install it with the other method? If you did it with the other method I can't help you. All I can suggest is deleting version 2.0 first before installing 2.1.
If you did an OTA download it should have said new version? Then you pressed save? When you start the app does it say version 2.1 in the splash screen?
How many email addresses do you have saved?
In the previous version if you had more than one email address in the list and you didn't check off the first one you would get this message: "
Failed. Please try again. Missing info." It was
expecting the first one to be checked (bug fixed). Three things are required: image, name, and email. However, it won't even let you try to send it without that information. It will tell you exactly what is missing before you can send it.
What is the exact message you are getting?
There are four responses you can get from the server:
"Failed. Please try again. Missing info." - part of the post didn't make it
"Failed. Please try again. Wrong key." - you trying to hack

"Done." - painting sent successfully
"Failed sending email. Please try again." - any number of things beyond my control
There is another message built into the code. It is "Failed..." something or another. It will occur if you have a network failure.
How strong is your signal? Edge or 3G?
I just sent myself a number of paintings with various combinations of email addresses checked off and they were
all sent successfully.
Is anyone else having this problem? Please tell me.
