Hei dude. I have a question about using the Micro SD Card with these devices (Mk4 & Q):

Although I understand, when using the “Delete PSBTs” function most, if not all, of the files already used should be deleted, which are recorded on the card.

In one of the menus near the “Delete PSBTs” function there is another function which is used to ›Format the card‹. If I format it, is it still suitable for subsequent transactions, without the risk of the wallets already created suffering from some “defect” when use it? Please let me know.
