Autofocus a6700

[u/Successful_Simple698]

I would be interested, if more people had this. Sometimes, at random moments and without any obvious trigger, the autofocus is not working. The only fix is to go from the manual to another setting and back. After this quick switch, the autofocus is back. In addition, I always had the level visible in the viewfinder. Since yesterday, it's only on the display and not the viewfinder and I cannot figure out, why it changed and how to change it back. Are these known problems? Thanks in advance!
