Plex Update problems

I have been unable to update Plex recently latest failed attempt 1.18.6.2348, All of the updates in the last few weeks fail to load and update and I lock up sop I stop them after 5-10 of trying? Does anyone have any ideas what might be the problem? Also, I use Plex B on my Ipad and for a while, I was getting updates every few weeks and it has been maybe 3 months since I have seen a Plex B update??

My Update problems continue and have been this way for maybe a month. Today I tried to installed Plex …2415. I use to download the plex update and the install via my QNAP App Center but lately, I have no luck doing any updates, can anyone determine what might be the problem Thanks
