Found number for 2018 GE. 31,969 VBM not counted.
“In Florida, notwithstanding opportunities for voters to cure missing or mismatched signatures, tens of thousands of on-time VBM ballots are still rejected every election. In the 2018 general election, for example, more than 1/100 VBM ballots received by local election officials were ultimately not counted, amounting to some 31,969 uncounted ballots.”

Its a tough read. Trust me, you won’t want to.
Actually, 2016 and 2018 in that same article.
“Of the more than 2.7 million VBM ballots cast in November 2016, over 27,700 were not counted, corresponding to a rejection rate of approximately 1.0 percent. And, of the more than 2.6 million VBM ballots cast in November 2018, nearly 32,000 were invalid, a rejection rate of approximately 1.2 percent.”
If you look at the chart of rejection by Age in 2016.
The seniors have the lowest rejection rate!
The 18-21 year olds have a 4% rejection rate.
