I have identified by trial and error that this one FILTER function is causing a massive "Calculating Formulas..." delay in my Google Sheet. This is the ONLY cause of the delay I have tested it extensively. MY solution right now is to add a "1" before the equal sign to turn the formula into text so then whenever I need to use the formula to retrieve and save its results I remove the "1" to run it and then put it back and refresh.
Of course this is not a good clean workaround.
Formula is:
=FILTER({FORMULARIO!C9:C}, FORMULARIO!J9:J<>"PAGÓ", FORMULARIO!B9:B=10, FORMULARIO!C9:C<>"", FORMULARIO!A9:A>TODAY()-5, NOT(REGEXMATCH(FORMULARIO!Q9:Q, TEXTJOIN("|", 1, FILTER(FORMULARIO!Q9:Q, FORMULARIO!J9:J="PAGÓ")))))
I'm looking for potential edits to the formula to reduce this humongous delay. Maybe turn it into a QUERY function?
