I’ve been reporting this exact same bug (app freezes on splash screen at launch) for 5 months now and have come to the conclusion that no fxxx are given (I’m bitchin despite being a software developer myself… because 5 months of 放置 is just too long).
I’ve enjoyed using the Pro app for about 2 years but for the last 5 months it’s back to pen and paper…
I’ve signed up for the beta so let’s see if you can fix this. I’m more than happy to help.
Also please consider adding a web browser based workout data entry page because relying on the app alone is just not ‘smart’. My view is that you are providing a service and so it should (ideally) be accessible from any platform/environment and not break when one of the access points has issues.
Also just had an idea… why not build the app to be a single page javascript based web app where the app lauches a stable browser environment and the user can then choose which version of the app to load.
