I've had two separate Coinbase accounts over the past 8 years, and this has happened to both of my accounts. The first account which I created around 2014-2015, was funded with 0.5 BTC. I didn't log into that account for years (until 2017 when the number was going up), and I painstakingly got back into the account to see that my balance had been reset to zero. I created a second account in 2020, and had a fractional amount of BTC and ETH in my wallet. Coinbase forcibly logged me out of my mobile app sometime in 2022, and I never bothered to try to get back in until today to find that my balance has once again been reset to $0.00.
Has this happened to others? I saw some articles from 2021 that claimed they did this to accounts that hadn't logged in for a number of years, stating that it was considered "unclaimed property" (and apparently claimable by Coinbase?) ...

"The proceeds from this conversion are then sent to the account holder's state unclaimed property office to be held until the owner makes a claim to recover the U.S. dollar proceeds of this conversion."
