Over the years, the only lens that I had an issue with sealing is the Panasonic 100-300mm mark II lens. So, I just don't count my two splash resistant Panasonic lenses (100-300mm and 35-100mm f/2.8) as really being up to Olympus/OM standards.
As I'm currently considering an offer on a used Pana 100-300 mark II lens as a weather resistant alternative to my Oly 75-300, I would be very interested to hear more details about the issues you have experienced.
I bought the lens used from my brick & mortar store (Hunts Photo & Video in Melrose, MA) in 2017. The next day I went on a whale watch in the Atlantic ocean.
I carried with me an Olympus E-m1 mark I with the Olympus 14-150mm mark II f/4-5.6 lens and my Panasonic G85 with the used Panasonic 100-300mm mark II lens f/4-5.6. I specifically did not mix the lenses and bodies, since people have mentioned that the rubber seals are slightly different sizes between Olympus and Panasonic cameras.
While the big boat (Privateer IV from https://www.7seaswhalewatch.com/) that we use for doing whale watches in the Altantic is typically high enough that we don't get splashed, I did get one or two splashes from the ocean on this trip. Note, both cameras had been subjected to splashes at least twice before that on other whale watches. Likewise the 14-150mm lens had been splashed in the past. Since it was new to me, the 100-300mm had not been splashed before.
When we got back to the car, I did my usual cleaning protocol. I carry a jug of distilled water (that I typically use in my Bipap machine for sleep apnea) and a towel. I rinse the camera and lens off in the parking lot, and dry them off before heading off to supper and then driving home. I zoom the lens in/out as I rinse it to try and remove all of the salt.
When I got home, the Olympus E-m1 mark I was fine. The Olympus 14-150mm mark II was fine. The Panasonic G85 was fine. But the Panasonic 100-300mm did not turn on. You could hear a slight grinding noise when the camera attempted to reposition the gears. I played mix and match, trying other lenses on both camera bodies (no issue), and trying both lenses on other bodies (14-150mm ok, 100-300mm was not ok).
Then I tried the rice method with taking uncooked rice, and sealing the lens in the rice for several days for the rice to absorb any liquid. It still did not work.
Finally in desperation, I hit the lens on a table, and then it worked after that. I postulate that a grain of salt got in the gears, and rapping the lens freed it up. Because it was in the gears, the body sensed that the gears were stuck and turned off the camera.
Since then the 100-300mm has worked fine, but due to weight I don't shoot with it that often. I did use it a few times this year (2022).
The 14-150mm lens was used continuously after that until I upgraded to the Olympus 12-200mm lens in 2020, though I've used it a few times since getting the 12-200mm.
When I used it the G85 has continued to perform well. I don't like the Panasonic way of doing things, and as I got first the E-m10 mark II and later the E-m5 mark III, I stopped using the G85 for anything but video. The G85 has an OLED viewfinder, which is easier to see with polarized sunglasses. The E-m10 mark II and E-m5 mark III also have OLED viewfinders, which tended to be the main reason I shot stills with the G85 in the later days.
The E-m1 mostly worked after that, but I did have two times when I had to send it in for servicing. The first time was to fix a sticky shutter in 2018 (which I don't think were caused by the wave splash). I did have to send it in a second time in 2019 where the USB and shutter release ports stopped working. It is possible that the salt from that wave splash in 2017 caused the problem, but the camera has been the subject of a few other splashes before and after 2017, so I doubt it.
I did take both the G85 and E-m1 along with my 2 normal splash resistant lenses (Olympus 12-40mm f/2.8 and Olympus 14-150mm mark II f/4-5.6) to Niagara Falls in 2018, where I took both cameras/lenses on the boat ride on the river where you get splashed for over 10 minutes.
