When we are talking about the pieces of software or messengers, what preposition should we use, on or in?

For example:

If you have any questions, feel free to drop me a line on / in Telegram.

Should we use on, in, or both of them are acceptable? And if both of them are acceptable indeed, is there a difference in meaning between the two?

If it's a software platform such as WhatsApp or Twitter you would usually say: on, by, or via.

If its a type of messaging (telegram, telephone, mail) you would usually say by or via.
