EQ bug firmware 1.2.1

A&H CQ20B Firmware 1.2.1 EQ Control Issues

Just upgraded to firmware V 1.2.1 from 1.2.0 on both my CQ hardware and CQ mixpad (Mac Air 13 inch early 2015 1.6 GHz dual core I5, 8gb memory, Big Sur V 11.7.10 - connection via cat5 from mac to CQ20 or internal wifi)

A given band of parametric EQ is initially adjusted graphically (by dragging the dot to a position on the screen). Subsequently and intermittently (ie. this happens often but randomly, not repeatably) becomes un-selectable for further adjustment.
The EQ band is still operable using the [non-graphic] slider controls on the lower portion of the EQ display (BW, Freq, Gain) which operate normally including visual representation on the graphic display EXCEPT that if I try to adjust using the graphic control, that band pops back to where it was previously (graphically) adjusted, and still refuses to be adjusted graphically.
Also - this is very interesting - switching to a different input channel and trying to graphically adjust that same EQ band pops the control to the position previously adjusted on the original channel: that band on ANY AND ALL channels is now takes that setting if I attempt to control it graphically (ie. drag and drop)

I tried a power cycle; the problem persists.
I tried a factory reset; the problem persists.
I tried a computer reboot; the problem persists
I connected via wifi; the problem persists
I connected via hard wire; the problem persists.

reinstall the CQ MixPad App …

I rolled back the firmware to 1.2.0. Works better now. Maybe sometime I’ll try the process again; now I just need a reliable working tool and don’t have much time to mess around with software bugs.
Curious if anyone has encountered this particular situation.

Yes, it was the same for me, reinstalling the MixPad app 1.2.1 solved the problem.
