dex nor smart view no longer working as advertised [fold3]
 

[sp1a.210812.016.f926u1ues1dvg3] a few months ago both worked. now when i try to dex to my fire-tv or roku i see the butterfly-flower background image with app icons on the top left of the television screen. i used to press the recent apps overlay button and there was a 4th button to use as a trackpad (no more). so i cant run any apps on the t.v.

also smart view no longer mirrors my cellular-telefones screen. when it first connects i see my fone screen/widgets on the t.v. for half a second and then immediately the screen flashes to the butterfly-flower background image (no app icons but a small white dot on the bottom rite). i can cast videos but i cant mirror. i tried opening email app on my fone and selecting app cast but it makes the email app into a smaller window on my fone but no change on the t.v.
