Hi @Bluemoon1 welcome back to the community, I've moved your post to its own thread as that's a different error message than the OP is getting. No network available usually means there is no connection to the internet. Can you check your Wi-Fi settings to make sure the tablet has a working internet connection?
@NeilO Thanks for your reply. Yes everything else works fine, and all other apps work on the same tablet. Wi-fi connection is good as my phone is on same network. I have uninstalled and reinstalled changed password but get same results.. As I said on my phone I can use the app perfectly.
Hi @Bluemoon1 that's a strange one. We'll need to ask our email experts to take a look as you've done all the basic checks already. I'll send you a private message so you can contact the moderation team with your details.
Try downloading the Bluemail email app. It works fine for me when I am in Spain.
