Safe Harbor 401(k) Contribution Timeline

Question about Safe Harbor 401(k) and is there a timeframe that the company has to make their contribution. My company offers a Safe Harbor 401(k) and only they do their match once a year. I was told we generally get the companies contribution after the first quarter in the following year, so after April of 2024 we’re supposed to get our 3% from 2023. Last year when I asked HR about the company contribution I was told “Typically, contributions have been made after the first quarter, in April or May, of the following year.” I have checked my 401(k) account and all three of my personal contributions for May have been posted to my account, there is no company match yet, and we’re past April/May as I was told previously. Can a company wait this long to give us our money from the previous year? I cannot find anything online that says if a company has a certain time limit to give their portion. Giving out their portion once per year loses a lot of potential interest gained throughout the year. As of now, money that could have been gaining interest since January 2023 is going on 16 months of no interest gained.
