I am new to stm32. I developed an RTC project, for stm32F446RE Nucleo, that displays date on 16x2 LCD, based on the HAL example. The project works fine. I tried to use the LL example, (to learn it too), to do the same thing on stm32L476RG Nucleo. The time is displayed right but I can not dynamically change the time as I was able with the HAL based project. I tried to use the set hour, minutes, day, month etc..  tried to use the Set_config, and even tried to use the same configuration routine I use at reset. Any insight in where I am going wrong?  thx

Only the person that has had THIS EXACT problem will be able to answer if you don't provide things like source code and hardware setup.

The main.c file the LCD is the LCD1602 Arduino shield with data at pins D4-D7, D8 and D9 and EN and RS, and D10 is PWM for backlight.
