How do you do airborne and amphibious invasions?

[Sokol]

Not new to hearts of iron, i played hundreds of hours of HOI3, but I am new to HOI4. I know you have to use the battle plan orders, have your airborne in an airfield region with a transport air wing / marines in a port region and have enough convoys, but when i finish making the orders and everything, the invasions just never happen.

Can someone run me by, step-by-step on what I'm supposed to do?

Seems you got everything done right, except this minor yet vital part, need air superiority for paras to drop and naval superiority for marines to set sail and go invade, even if the enemy ain't got any planes or ships to counter it, you need at least one.
And that would be superiority from kick off point across all sectors they travel through and over/at the target.

Paras:
Create paradrop order from airfield with sufficient transport planes (that do not have supply mission active)
have around 70% air superiority through ALL air zones crossed when you launch order using the arrow above the generals icon along the bottom

Marines:
Create amphibious assault order from friendly port, designating enemy coastline
have around 70% naval through all naval zones crossed and launch order

You're likely not having sufficient air superiority/naval supremacy to launch the orders

Yesss thats most likely it, thats a feature that wasnt in HOI3 and i often forget it exists, I'll have to try this out when the game is playable again and see if it works, thanks
