Okay.... Updated my DL32R the night of a practice.... hehe I'm an idiot....
iPad pro is happy....
iPad Air 2 is happy
iPad 3 old school is happy, just as laggy as ever - time to replace it.
Now, this may or may not be related, but after updating MF, I went to chrome and noticed that my typing was lagging on the iPad Pro. Closed out Chrome, reopened it, and it was responding slowly.
My touch was not being recognized. Closed it out again. hard reboot
Haven't seen the issue again. This could be Chrome, it's wonky anyway.
