Question about deleting integrations

I’m having trouble finding 1 tp link plug in the new ST app. The integration finds a dozen other tp link switches and plugs. Even found the other 3 from the four pack I bought and installed at the same time. Has been over a week and the communication between the two is there as a recent name change of different device shows up. Question is if I delete the tp link integration, will all the devices and asscociates routines be lost and I need to manually re enter them when re linking the integration? Many thanks!
