One commonly encountered issue while working on this feature is that of missing mandatory values in XRPC types.
The client will show an unhelpful message warning that the server might be out of date.

However it's possible to patch node_modules\@atproto\xrpc\dist\types.js to something like this to get more useful error messages:

class XRPCInvalidResponseError extends XRPCError {
    constructor(lexiconNsid, validationError, responseBody) {
         super(ResponseType.InvalidResponse, exports.ResponseTypeStrings[ResponseType.InvalidResponse],
+        'Validation error: ' + validationError?.message,
         undefined, { cause: validationError });

The Replies and Media tab cannot be tested yet, since the typescript client hides such tabs to non logged in users (or it could be patched)
