I've been using the yahoo mail app for a while now, and have run into my first problem. Moto droid non rooted, running frg22d. For some reason, when I get a message from gmail, I get about 40 lines of code/gibberish. I noticed this on about 5 emails today, so I reinstalled the app.
The messages that were screwed up, are now fixed.
But, as I received more gmails, the jibberish thing started again. The old emails remained fixed though.
What I've found is that if I want to see messages properly, I have to either reinstall, or do the "remove account" essentially signing out then back in.
I've not seen any other posts, or anything that indicates it is a known issue. I'm guessing its a brand new malfunction, and people will begin to notice.
So if anyone is using the yahoo app, let me know what happens if you get a gmail.
