Missing BTC from blockchain.com account.

Hello all! I have had an account with blockchain.com since 2017. Up until recently, I had built up my private key BTC wallet up to 0.127xxxx bitcoin. I usually open up the app about once a week. A few days ago, I noticed that wallet was showing 0.083xxxx bitcoin. I don’t know what happened. I also know nothing of anything happening with bitcoin, and am out of the loop on any news.

There are no listings in the Activity on the account to reflect this. Just the standard purchases I’ve made to buy bitcoin.

I have not ever made a single “regular” transaction with bitcoin, like to purchase anything or even between another person.

Any help is greatly appreciated! Thank you!
