Regarding this, some or most non-custodial wallets would not allow you take screenshot of your seed phrases in order to discourage you from storing it on your device storage or immediately uploading it online which is a bad security practice.
This feature is very important especially for users who don’t realize how dangerous taking a screenshot of your wallet seed can be. This is why any reputable wallet must have it. You can think of it as the security measure on most platforms that hides your account password on the registration or login form.
Even if you delete the screenshot, it’s still not safe as there is still a risk that it can be recovered.
Not just screenshots, it’s not recommended to store your seeds digitally, and if you do so,at least make sure to encrypt your files.
I'm glad to hear this, I have never tried to screenshot my seed phrase before because I know the implications of doing so, nothing is entirely safe and secret online, one way or another information can be hacked. The safety of your seed phrase is 100% your responsibility, you cannot blame your wallet provider if it is compromised in anyway, that is every wallet owners must make the security of their seed phrase a top priority. Seed phrase is the price of self custody, without it in your custody your coins can become somebody else's coins if they import it to another wallet.
