Mine do that occasionally also. It’s all about their position on the tank bottom, also the rubber can get bunched up or dislodged at the sensor. One of my sensors wires broke off at the solder joint, I repaired it.
Just try to reposition it on the flat part of the tank bottom, make sure it’s clean and no rust or anything.
Funny thing I removed the sensor, sanded the bottom of the tank and put dielectric grease and put it back on the bottom of the tank......instantly the monitor recognized it but the phone app did not......
