Hello! I have downloaded Anki only for a few months and am new to the forum.
I recently updated Anki to Version 2.1.26 (70784154). Sometimes when I open Anki on my desktop and put my computer to sleep, my study progress from the last session is lost when I wake up my computer. The cards that I had revised showed up again, even though it was meant to be shown again around a month later. Sometimes, Anki would shut down itself when I wake up my computer, which also resulted in progress loss.
It seems that it also happens when I leave my computer idle for a period of time, that Anki would just restart itself.
I can still manage to save my progress by closing Anki right after I finish studying my cards and decided to have a break. However, it is quite troublesome as there are times when I have to spend time looking at my notes for a question, which closing Anki interrupts my flow, and Anki may show a different question the next time I open it.
Any insight is appreciated, thank you!
