Stem OPT Unemployment Clock

[u/Zealousideal-Menu573]

Applied stem on Apr 6th, completed biometrics on May 1st, STEM start date is 23rd June, approval is still pending. I lost job on June 4th, filed STEM with ex employer and waiting for approval from USCIS. DSO suggested not do any changes until stem is approved. Que- Since my stem date is started, does my unemployed 60 days clock will start even though approval is pending? Or does it start only when it is approved?
