Moved emails

I Need some help please. Ever since the IOS 9 update ast well as the 9.1 update - my email has gone completely WACKY,

I have 2 Gmail accounts as well as an iCloud account. Not everytime, but at least every 3rd time whenever I go to delete or move an email - I completely lose my ENTIRE INBOX!

SO far I have been able to locate most of my emails, but they always end up with the title of "NO SENDER". Once I place them back into the inbox, the TITLES don't come back to the replaced emails.

I also am having difficulty with a hesitation in my keyboard, as well as being KICKED out of any number of Apps without rhyme or reason. If there is anyone who can offer me ANY ASSISTANCE with these matters, I would greatly appreciate it.

Thank you,

Pat Clark
