Should I go ahead and upgrade to iOS 13?

Hi everyone,
I use an iPhone 8 with VoiceOver. I haven't yet upgraded to iOS 13 as I have read about the various bugs contained within the software (thank you AppleVis) so as a result I am still using the latest version of iOS 12. However, in the last couple of days I have noticed some major accessibility bugs with certain apps. For example, I am currently unable to vote in polls using the Twitter for iPhone app or 'like' tweets when the tweet is open. Furthermore, I have also noticed that I cannot navigate through the 'browse all' section in the 'search' area of Spotify – VoiceOver just navigates to the playback controls.
Does anyone know if upgrading to iOS 13 will resolve these issues (obviously apps are now being updated to work with iOS 13, not iOS 12) or should I still hold off because of the bugs that are present in iOS 13? Is it worth me waiting for the release of iOS 13.3?
I don't particularly want to upgrade my phone as I bought it upfront only 18 months ago so I feel that now is too soon to go out and buy a new phone. If anyone could give me advice on whether it is worth updating an iPhone 8 to iOS 13, that would be much appreciated but advice from anyone regardless of which model they use would also be helpful.
Thank you and I look forward to your responses,
Alice
