v2.3 upgrade has completely destroyed my system

SFQ3YU5t

I upgraded to 2.3 on asiair couple of days ago and accuracy on guiding is absolutely terrible
Have been using an AM3 with ZWO 533MCPro with ZWO 1200 guide camera with Redcat51III, Apertura 75Q, Askar 103 with WO 120 and SV190 guide scopes for a year with great success
Averaging .3 to .7 guiding using ALL configurations until 2.3 upgrade
Was using Skywatcher GTI with .5 to 1.5 accuracy and updated to AM3 for solution
My lightest configuration suing 533 best guiding 1.5 to 3.5 - HORRIBLE
Changed All cables, ALL HOUTS with adjustments by Peter Zelinka and others, and nothing works
Looks like my $10 GRAND investment has gone down the drain
Wasted 20 hours imaging recently to misguiding issues
Cannot find information on rolling back to previous versions
Can someone PLEASE address this issue with a logical suggestion
VERY FRUSTRATED ZWO USER

You can roll back the firmware on your asiair back to factory through one of its menus when you're connected to it with your controlling device (phone/tablet).

After you've done that your app version on your controlling device has to be uninstalled and an older version of the app needs to be installed. This is because updated firmwares are bundled with updated app versions and if you connect again to your asiair with an updated app it'll inform you to update the firmware on your asiair if it's installed firmware is older (or factory), you do not have an opt out option for this (not to be confused with the opt out option you DO have for the app version you're using).

I have been using older app versions for a very long time as usually a new one will introduce random issues like yours which had previously been working fine.
