I was made aware several days ago that my flight from ZZZ-ZZZ1 on operated with vertical stabilizer probe covers on. I did the walk-around and did not notice the covers on the probes. In my years of flying this type aircraft; I have never had the probes covered. I entered a write-up after landing that the FEEL DIFF light came on several times in flight; but the aircraft operated normal. Yesterday I spoke to Maintenance in ZZZ and I asked what color are the probe covers normally. He said normally X color; however they were short on supplies and in many cases used other methods to cover the probes. Also; Maintenance mentioned this was a new procedure and did not have all the necessary standardization and procedures in place. In today's environment; we have all types of distractions going on; I don't believe I need to list them. This is a challenging time for all employee groups which can cause mistakes and errors. I'm sure Maintenance did not intentionally not remove the covers.
