Hi,
I have set up the SendGrid mail as a test following your very clear instructions and published the app to .app.appery.io
Testing the mail functionality and it works fine in a web browser from my desktop and also from my iPad using Safari, but when I try it on my phone (android), I get the message "error sending email. Permission denied, wrong credentials". Any idea why it would work ok from browsers on two platforms and not the third?
Hello,
Should work for different platforms. Did you change anything in Android sources?
No nothing changed, everything done in the UI until I get final OK from my boss then I will make changes to CSS only.
Any chance it could be to do with Android version?
What library and Android versions do you have?
I'm embarrassed to admit Android version 2.3.6, not sure what is meant by library.
I believe that is the answer as a colleague who is a little more up to date than I am ran the email send without any problem.
No worries
