I forgot to mention that after I finished with the nasal spray I was doing daily morning and evening nasal rinses to keep the sinus clear which really helped but got tiring. I found fairly inexpensive device to use instead of the daily nasal rinse - SinuSonic (https://sinusonic.com/) and have been using it for almost 2 years and it works well for keeping my nose breathing clear. This past week I found another device and ordered it to see if it might work better - ClearUp (https://tivichealth.com/). It's more spendy but if it works it will be well worth it since this one should last longer and the SinuSonic last for 6 months and you have to replace it.
