I have a Mi3 with the miui.eu version MIUI 4.7.25, I used to have the same username for me mail accounts, but in this version I can not have two accounts with the same username (firstname.lastname@example.org and email@example.com). It is strange because previously I have used a MIUI version of miui.es and I can do it. Now I should use another android apk to avoid this problem but I like the mail MIUI apk . I dont know if I dont configure the mail apk properly or it is a bug. Could you help me? Thanks in advance.
