Same thing here. Using ESPHome almost identical config from the tutorial except for my wifi secrets.

If anyone is interested here is the ESPHome config I arrived on:

substitutions:
  name: "vindriktning_01"
  friendly_name: "vindriktning 01"
  project_name: "ikea.vindriktning-sensor"

ota:
  password: !secret freindly_password

wifi:
    ssid: !secret wifi_ssid
    password: !secret wifi_password

    # Enable fallback hotspot (captive portal) in case wifi connection fails
    ap:
      ssid: "Ikea-Vindriktning-01"
      password: !secret freindly_password
      ap_timeout: 30s

esphome:
    name: "${name}"
    project:
          name: "${project_name}"
          version: "1.0"

I’ve been using Synching to nightly backup my cellphone pictures for about 4 years now and it is still working just fine. I have a folder that gets pulled to my phones with edited photos and the phone cam foler gets pushed. Worst thing about it is android sometimes stops allowing the client to run if you haven’t opened it in awhile.
