Wife SS increase to 50% when I collect my SS if born after 1954?

My wife was born 06/16/56. She started collecting SS at age 62. June of last year. She has been collecting less than a year.
Is she eligible to increase her SS to the ½ percentage that matches my retirement age if larger than what she is collecting? Which it will be. I plan on retiring at age 65, at this time. Next year.
I read an article that there was a spouse benefit change that if she was born after 01/02/1954, and starts collecting her SS before I retire she is committed to the first amount, and not eligible for the spouse benefit increase. Is this correct?
I read that there is a “Start, Stop, Start” option if it is done within the first year of collecting, and you pay back what you received. Is this true?
Her SS is not that much, so we decided it was worth it to just start collecting at 62, and increase it when I retired. I was not aware of these changes until recently.
