Not the most challenging grid around, and some nice ideas in it. Particularly like the def for 7A7AMating expert sets matches messily, a tad reluctantly, and having no time? (5, 6)[-----------], and 19A19ACreature seen in many online videos, and in Africa too (3)[---] is cute.
I do have a few quibbles around style, mainly with how some of the deletions have been played fast and loose. e.g. in 1A1ACommuter's choice is robust - no nonsense (3)[---] the deletion of ROT is split over the fodder. It'd be more standard to either indicate this or delete each element separately (but if you were deleting BUS1ACommuter's choice is robust - no nonsense (3)[---] then the type of construction you've used would be perfectly valid.
I don't buy Ivy as a fair def for 3A3AIvy that's tough containing various aromatic resins primarily (7)[-------], as the type of word used to define the answer needs to match the answer's type of word (i.e. no defining nouns with adverbs). Here it seems like you're defining a noun with an adjective (or using a particularly lax reference dictionary, which should be called out in the preamble).
Some letter selections like 6D6DThird-oldest Greek god has guts (5)[-----]'s Third-fodder for D and 7A7AMating expert sets matches messily, a tad reluctantly, and having no time? (5, 6)[-----------]'s a tad [OF] fodder for F are a bit loose, as are some of the deletions like 7A7AMating expert sets matches messily, a tad reluctantly, and having no time? (5, 6)[-----------]'s having no time to be removing only ONE 't'.
Most people are also much happier with deceptive capitalisation of words than they are with deceptive decapitalisation, but regardless I think charading sprint to ERS off of a Harley Davidson motorcycle is quite a deep cut. This all did culminate in me WOFing the answer to 18A18A"Boss, how's it goin'?" "Look out!" (5, 2)[-------] and not bothering to attempt to retroparse anything beyond the first charade. It might just be me overlooking something obvious / simple, but given the other things going on in the grid I don't feel like trying to potentially squeeze blood from a stone.
