is anyone having network issues with galaxy z fold 3??

Hello all…..I have been using the work around found on this post for a while now and it works almost perfect. I do get a random message sometime that its searching for network but it seem to connect immediately… the call quality is much improved and messages send with no problem, 5g seems to work fast and efficiently. Today i got an software update ending in BVA9 and I was hoping this was a permanent fix. This does not seem to fix anything for me...after the update the phone went into searching and I had to manually select T-Mobile .The connection bounced between H+ 3g and 5g with super slow internet browsing. I have only tested this for a short time in my home but that was enough for me to reapply the workaround to get things working again
