This has been an ongoing problem, but seems worse lately. If I save an email I'm writing into Drafts, often when I take it out again to write more, the send button is grayed out and I can't get it off the screen. I have to do a hard reset and lose anything I've written since I re-opened it. (Yes, by now I check to see if the send button is active before writing more.) It seems to occur at random - it will work just fine for a while and then problems. I can exit the iCloud email app and use any other app without issues. But the email app is frozen from that point on with the draft on the screen. Anyone have an idea of why this is happening?
