Hi,
I am not sure if you have fixed this issue or not, but thought htis might be helpful for you.
I use an appcalled boldbeast recorder. it is a free app on google play.
I can record phone calls, meetings, and leave myself voice memos.
a word of warning though, it has been working well for years, but as of a couple of weeks ago I keep getting a message stating Android only allows one recording app to run at a time and I must uninstall or force stop all others, well the only other thing I have is a paid for app, which I did indeed install a couple of weeks ago - it allows me to transfer vinyl to my phone via a usb record player, but I forced it to stop and that has not fixed this issue - could be my phone as now the speakers are playing up, so might not be boldbeast clashing with anything.
However this app has worked well for me for many years, you can set it to store files on drive or sd card, or other cloud area if you do not want to keep them on your android phone.
I am disabled so it is super important for me to record conversations as I can then go back and listen to them.
I am in the UK, here it is permissable to record your own conversations for personal use. It is not something you could take to court , but handy nonetheless.
I hope this helps.
