I am using Khoi Hoangs ESPAsnyc_WiFimanager ESPAsync_WiFiManager which is performing fine, except one bothering issue:
From the moment when the ESPAsyncmanager class is initiated/inherited until the moment when a valid WiFi connection has been established no screen output possible/performed (using LVGL) within this time. This results in the situation, that one cannot perform user dialogs, f. e. to notify the user for using the Config Portal for connection. The screen remains dark. I have searched the source for a possible reason for omitting screen output, but did not find any. Any help is highly appreciated.
