Latest update? Which version specifically?
Might be related, but did you install LED bulbs in the garage door opener? There was another thread about homelink issues and I learned from there that normal LED bulbs really screw with the RF signal. Homelink on my Mustang never had that big of a problem but the Model 3 is much more sensitive to the interference that the LED bulbs emit. I recently switched to Genie LED bulbs that are specifically designed for use in garage door openers and that completely elimated my problems and doubled the range too.
