Expected behavior (the as-is before 18.22 update) -> connect to Bluetooth, acquire weather data, disconnect Bluetooth. Weather data remains available until obsolete.
Now (since 18.22 and still the same after 18.23 update) -> connect to Bluetooth, acquire weather data, disconnect Bluetooth. Weather data remains available for a few minutes and then goes blank.
I wrote to support via e-mail and not even an automated message was sent back. The chat support, on the other hand, was always kind and helpful but unfortunately nothing seems to solve, therefore this must be a bug.
As an owner of a 255 for little more than 4 weeks, quite frustrating.
