Many financial related apps don't work because a beta is not an official / approved release
I'd have to state that all my apps have no issue updating ... even my banking app works (and updates, and no it's not Fidelity)
Go to (phone) Settings > Apps > Google Play services ...
Force Stop (lower right)
Storage > Clear Cache
... retry updates
Hello @littlecloudgz ,
During beta program, the software is not yet certified by Google, and therefore Google Pay and other secure services may not work. We apologize for the inconvenience and will post a notice once it becomes certified by Google. You may try again at that time.
Fidelity has been notified by some of our members of the issue and are working on a resolution.
