XL4 extremely slow

I've had a Premiere XL4 for a couple of months and have now received the 20.4.6 update. Everything is now very slow. Opening a folder in "My Shows" takes 20s. When doing a search, I get the spinning ball when I choose a show. It's also slow to get back. Furthermore, most of the time if I want to set up a OnePass, I wait for a minute or so, then nothing happens. Then I click again and sometimes the OnePass window comes up, other times nothing again. And when I finally manage to get into the "set OnePass" screen, after a long wait, I'm out and the OnePass did not get set. Sometimes it works and sometimes it does't.



I had the same problem with my Mini before the update. If I changed a season pass on my mini, the changes would not go through on the Premiere. After the update they sometimes do and sometimes don't.



I can't say for sure that all this is happened after the 20.4.6 update, because I had issues with speed before that as well. But things have definitely gotten much worse. I just spent 10 minutes trying to set a OnePass three times only to have it not go through in the end. However, if I switch to SD menus I will be able to set the Season pass.



Also, just now I tried to delete a OnePass and it wouldn't delete it either. However, that worked yesterday.



Does anyone know what's going on here? I have rebooted several times.



I also want to mention that I have 90 Season passes. Is that a lot? On my Old HD XL changing order in the Season Pass manager took forever. I was pleased that the Premiere was so much faster. At least in the beginning. Now it takes more that 10 minutes on the XL4 and I don't know when that started.
