My Question or Issue

Hey so for the last couple of weeks I've been having issues while trying to listen to Spotify over a Bluetooth speaker a song will play for 5 seconds sometimes up to a minute before the sound cuts out but playback continues. The crazy part is that I've had this phone and speaker and used spotify premium on it flawlessly for over a year , but just past couple of weeks this issue has arisen, any help will be appreciated.
