Any help to correct the intermittent dysfunction of this keyboard? Using it with my iPad Air 4th Gen. Normally the keyboard will suppress the virtual keyboard of IOS and will have illuminated keys- however, more often it will not do that. Virtual keyboard is popping up and can’t be suppressed, and illuminated keys are only a matter of chance. Have done all updates- no difference. Is this keyboard for the garbage can or is there a chance to get it working properly? Is Folio touch a misnomer for Folly Touch? Would the apple smart /or magic keyboard work more reliable?
