Runna app garmin forerunner 265s pace gauge stopped alerting.

I am currently using a garmin forerunner 265s watch and a plan of Runna. Up until a few weeks ago I was getting pace alerts when running too fast, slow or in range when it had different segments. It never used to do it on warm ups, cool downs or recovery runs. I have no idea how but it stopped working and no longer displays this screen. I have tried Googling the problem and followed all the advice and guidance but nothing seems to be working. Has anybody else had this problem and how did you resolve it. I think it stopped working the same time I started a trial on Trainingpeaks but don’t think that is synced any more as I don’t use it. I’d be really grateful for any advice. Thanks
