imo, you should spend sufficient time on a sentence, especially when starting to read. Then try to explain or translate in your own words, then let people check.
If natives or teachers are too difficult to reach out, that’s what forum is for. For this community particularly, Japanese Language > Grammar or just these threads – Short Grammar Questions (Part 2) and The quick or short Language Questions Thread (not grammar) – but don’t hesitate if you feel a need to open a new thread.
I’d also recommend hiding English translation. That’s not your own comprehension.
At least, I am sure that taking time to comprehend by yourself matters for leaps in comprehension.
Another thing is sentences on WaniKani, even at low levels, aren’t necessarily the easiest. Low levels somewhere else – Tadoku or Natively – may be easier.
