Hi, good job!
I have a trouble, with ESPAsync_WiFiManager:
1.- Start Captive portal, and I config SSID and Password for mi mobile wifi AP.
2.- Save data OK.
3.- manual Reset ESP8266 and start Config Portal for 30sg (I configure), and next connect with my mobile AP perfect.
4.- If I switch off my mobile AP, and reset ESP8266, then:

ESPAsync_WiFiManager Version v1.3.0
[WM] RFC925 Hostname = ConfigOnStartup
Stored: SSID = , Pass =
Opening configuration portal.Open Config Portal without Timeout: No stored Credentials

And no Stored SSID and no Pass !!!

Can you help me ?
