Hi @rpcosmo,
when I try to open your project it takes forever to load and the page becomes extremely unresponsive - even Google Chrome alerts that the site is unresponsive and it completely freezes on the scr_principal blocks… On that particular screen there is also an error but I cannot try to get rid of that because it completely freezes…
However I managed to install your app anyways by changing the App Package name. I had to replace the last segment. There are some rules for application IDs:
- It must have at least two segments (one or more dots).
- Each segment must start with a letter.
- All characters must be alphanumeric or an underscore [a-zA-Z0-9_].
@domhnallohanlon this might be something Thunkable should implement since the package name was automatically generated by the system when I remixed it (com.gmail.christiancraik.6118tool)
@rpcosmo besides the above: do you really need dozens of screens?
I think your app is a little too blown up
