I do not use Lastpass or other password managers and nothing in Accessibility is enabled- I have done some Googling... getting more blank email contents over time- Amazon.com order confirmations, UPS tracking info are the latest and they do appear normally on PC and Mac's. The headers etc are there, just blank contents... Nexus 6, Marshmallow, latest AquaMail... other settings to check, uninstall/reinstall AquaMail, or will an OS clean flash resolve the issue?
Thanks.
