@ericihli could try putting ^:flush-dom on the dispatch of [:mnemonic-submitted-for-calculation ..]

Looks like the reagent render queue is not being flushed in-between the submission & calculation

Just tried that. No joy 😞

Hmm. Is ^:flush-dom on both events now or just the one?

Tried all three combinations.

I noticed this Reagent issue from way back and thought it might be related but I'm struggling to verify due to my unfamiliarity with the tech/tools https://github.com/reagent-project/reagent/issues/241

Or :dispatch-later with a short timeout for the computation fn https://github.com/day8/re-frame/blob/97a5c3795820cd37a976b62e2ac3cb1f626d2467/src/re_frame/fx.cljc#L95

All right. That's a solution. Thanks. :dispatch-later with 1ms doesn't work; 20ms does work.
