Male sling surgery and still some leaking

Hi, I am 69 yes old had my Prostate removed 3/2020 right as Covid was starting. Gleason score of 3+4=7, I get my PSA tested every 6 months now and has always been <.01 so that all turned out good.
After surgery I had major incontinence problems but as time went on I got down to 1 or 2 big pads a day. It was mostly stress incontinence but even that was pretty annoying. After a few appointments I decided on the Advance sling surgery which I had beginning of this past December. It all seemed to be a success for the first couple weeks but then it seemed like I had to go very often and I better go quick or there's going to be some leakage. So now I went back to wearing a big pad again of which will last 24hrs. most of the time. Then I also developed a good cold with lots of coughing which caused some extra leakage but not as bad as coughing before the surgery. Now I also started getting up probably 3 times a night to pee.
I went to a follow-up appointment a month after surgery and was told my leakage now is probably due to urge incontinence. They put me on 5mg daily of Solifenacin (Vesicare) and said it should help but it's going to take at least a couple weeks before it starts to help.
Just wondering if anyone else has had this problem, because needless to say I am a bit disappointed right now considering right after surgery things were looking pretty dry!!!
