Thank you so much for everyones reply!!

I think part of the issue is i have the electrum app on my mobile device and when checking the settings it is a watch only wallet.. i want to enter the btc addresses to send manually but in the app it doesnt allow that.

I downloaded the electrum application on my windows device but i dont have the secret phase as it was on my old phone.
I do have the master public key but dont have the wallet file to upload on my computer

Are there any suggestions of how to open the wallet & change it to not watch only to proceed on my computer?
Or to get the wallet file / secret key?

Appreciate all of your support!

Hello, i have had some btc in my electrum wallet for some time but can't seem to get it out. When i try to scan the qr code for an invoice or external wallet it says 'unknown invoice'. The electrum app is on my phone & im not sure what to try next. Appreciate any pointers.
