My Galaxy note 10 plus pauses wireless charging when using Facebook messenger only.
Thanks for reaching out. I know this may seem like a silly question, but are you taking your device of the charger when experiencing these symptoms?
No, and I can charge my Galaxy S9+ while video chatting on Facebook messenger.
Wow! The Samsung external fast wireless charger, can charge from my other external charger and wirelessly charge my S9+. Glory to God through Jesus Christ!
