Metabones changing fstop by it self

Not sure if this is the place I should be posting this, but here it goes.

Guys, I have the latest firmware of the Metabones Smartadapter IV and I've had some serious issues on my last jobs.

Issue 1 - the fstop changes by it self while filming. Lets say I set my lens to f4 and I'm happily shooting something...from time to time the fstop goes to f1.4 and then it comes back to f4 in a mater of seconds. This, of course, gets recorded...which renders the adapter useless.
Issue 2 - The Canon 85mm 1.8 used to work wonders on my Sony A7II using phase detection af...now it hunts back and forth A LOT.

I've written the Metabones support team but it's been a while and I haven't heard from them.

This is a MAIN work tool for me and I need to have this fixed ASAP!

Are you using a grip battery - in particular the vello one or a third party? Try turning the battery grip off
 
Yes, I'm using a grip but I've been using it for a looong time and I've never had this issue before. I'll do some testing though.
