Yeap it's always a good idea to make messages short and easy to read.

Thank you ! do you have guidelines on the timing between shorter messages ? 

few seconds  ? 10 seconds ? else ? if there’s a link to an article pls advise

HI

still have a pbm

cannot set up multiple dm replies to smne who commented on my reel.

I should be able to send multiple messages, right ?

Depends on how long the text is, you want to give people time to read - I usually go with 5-10 seconds.

As for the comments trigger, yes, there are limitations on the first message. More details here: https://help.manychat.com/hc/en-us/articles/14281316989724-Instagram-Post-and-Reel-Comments-Trigger
