I’ve been charging to 90% lately and my range keeps going down. 3.29 % after 1800 miles on a two month old car is not right. It would appear that this range loss is not coming back. Every time I charge the range goes down further. Tesla, of course says battery is normal. Appreciate any thoughts.

Pretty normal, but hard to tell from historical data since newer models make degradation more obvious for the same amount (older ones hide the some initial amount).
There is a sort of "break in" period where the battery rapidly degrades a few percent, then that slows down greatly and levels out.
It's also worth noting that the TeslaFi extrapolations suffer from some rounding errors (mostly relevant for low states of charge) and battery temperature effects (your car reports slightly less available range/percent when colder, anything below about 25C/77F by my findings).

Why is your battery report set to charges 50% and higher? A charge to 50% isn't going to give the most accurate range estimate. See what happens if you change it to 60 or 70%

Also, your range drop happened drastically and recently. Have you changed your driving or charging patterns since quarantine?
And just noticed. 947 charges over 1800 miles? I've had 730 charges over 46,000 miles

If so, that would make a lot of sense. The other possibility is that the car is just left plugged in and does that "I'm going to stop charging now, but in a couple hours I'll top off" thing. I stayed plugged in for a weekend at a hotel once and ended up with 38 charge records
I thought about that, but when I checked Teslafi those charges were within the purchase time frame with the new car. The number of charges seems crazy because I’ve only had my new car for a couple of months. There has to be multiple charges lumped into one. I’ve only charged once a day that I can recall since I got the new car. 70 days should only be 70 charges, right? I just checked the total number of charges..9 at 90% 87 at 80% and 2 at 70%.

So you had a previous Tesla? I think TeslaFi knows about every charge cycle from both cars - that's the 947 charges.
But within the timeframe you selected you've had 98 charges. Ever left the car plugged in over a weekend or a few days with sentry running? Look at this....
the LR RWD was also grossly underestimated out of the box at 310 originally and later increased.

Yeah my LR RWD technically hasn't lost any miles. It started at 310. And I still have 310...... Just forget about those additional 15 miles they added along the way from efficiency improvements
