Equipped with Garmin GTN750/GDL-88 with full ADS-B in/out capability. The Traffic Information Service (TIS)/ Flight Information Service (FIS) status flags both showed the system functioning with full capability. The weather page of the 750 showed TAFs/METARs/Winds etc and the Last Update status field said 'less than 5m'. I was using Seattle Avionics' FlyQ software on my iPad. It was updating via cellular modem but did not have a connection to a non-certificated ADS-B capability. VFR northbound on V25 [at] 8;500 feet enroute LTJ VOR then west through the Columbia George then north home to BFI. Clear flight conditions with lots of smoke at lower altitudes due to many forest fires. In contact with Seattle Center for flight following.'[Aircraft X]; Seattle Center; will you be going around or above the TFR North of Madras.''Center; what TFR; there's no TFR on my FIS-B.''[Aircraft X]; Center; yes there is a TFR. Please advise...'I opened my iPad and the TFR was on my FlyQ. Imagine my surprise. I went to the GTN750 map page and scanned around and other current TFRs were visible but not this one. I checked the FIS status and it was still 'less than 5 min.' Using the FlyQ moving map; I navigated around the TFR.Continuing northbound near LTJ the same thing happened with another TFR. It was present on my iPad but NOT on the Garmin; yet other TFRs were present on the Garmin. The FIS Last Update still said '< 5min'.I spoke with the local FSDO this morning and they couldn't explain it.
A pilot with sophisticated navigational equipment was surprised to be advised of a Temporary Flight Restriction (TFR) by ATC. For unknown reasons; it was not depicted on his primary GPS/Multifunction display.
