no uploads despite sync and connected via bluetooth

iphone user

garmin edge 530 user

edge has BT enabled and phone paired, indicates connected in the top bar of home screen.

phone has garmin connect, paired with edge device

connection was fine and uploads have worked via bluetooth for years... since start of month 3 activities that have not synced... status on both connect and edge show "sync in progress" but no files are uploading.

manual upload push didn't work

unpairing, disabling BT on both phone and device, restarting and repairing did not work.

attempt to pair with wifi instead of BT... didn't work

what am i missing?
