Were it not for the matter of the folders ...

Hello Everybody. I bought this app a few days ago because I wanted to see what features I also (I have previously only used K9) on offer. Based on the positive feedback I thought it was worthwhile. Basically, this app is perhaps really not bad at all, but I have the problem that I can rarely switches to other folders. This means that if I moved a mail to a different folder (other than the Inbox), I no longer have access. But once he shows me, although the other folders, 2 min. Later again not. Unfortunately, access not succeed. Perhaps this is only a problem on my part. That's the only reason I can give only 2 stars for the app. Everything else seems tidy and reliable. But for me it is not suitable. Too bad.
